United Airlines Cargo tracking

What is United Airlines Cargo?

United Airlines Cargo, commonly referred to as United Cargo, is the cargo division of United Airlines, one of the major legacy carriers in the United States and a member of the Star Alliance global airline alliance. The division operates primarily by using the belly-hold capacity of United Airlines' passenger aircraft rather than maintaining a large independent freighter operation. This model allows United Cargo to move freight across an extensive domestic and international network, drawing on the flight frequency and geographic reach of one of the world's largest passenger airlines.

The history of United Airlines traces back to 1926, when Varney Air Lines was founded as the predecessor company. United Airlines itself was formally organized in 1931 as a subsidiary of United Aircraft and Transport Corporation. Air cargo operations began in earnest in December 1940, when the airline inaugurated what is widely regarded as the United States' first dedicated all-cargo service, running Douglas DC-4 aircraft between New York and Chicago. In March 1941, United joined American Airlines, TWA, and Eastern Airlines to form Air Cargo Inc., a cooperative freight enterprise that conducted significant cargo operations during World War II.

In later decades, cargo remained a supplemental revenue stream carried in the bellies of passenger aircraft. The airline resumed dedicated cargo flying in 1997 after a 13-year break from freighter operations, deploying McDonnell Douglas DC-10 freighters on high-demand Pacific routes. Over the years that followed, the operation evolved into a distinct, branded business under the United Cargo name, with its own specialized products, customer-facing systems, and a joint venture with Lufthansa Cargo covering transatlantic routes.

• Founded: United Airlines traces its history to 1926, with cargo operations formally initiated in December 1940 and the modern United Cargo brand developed from the late 1990s onward
• Headquarters: Chicago, Illinois, United States, with primary hub operations at Chicago O'Hare International Airport
• Parent company: United Airlines Holdings, Inc., parent of United Airlines, Inc.
• Brand name: United Cargo, also referred to as United Airlines Cargo
• IATA carrier code: UA
• AWB prefix: 016, the standard Air Waybill prefix for all United Airlines Cargo shipments
• Fleet basis: Belly cargo capacity on United Airlines passenger aircraft, including Boeing 737, 757, 767, 777, and 787 series and Airbus A319, A320, and A321
• Cargo alliance: Joint venture with Lufthansa Cargo covering transatlantic routes, plus interline partnerships extending the network to additional worldwide destinations
• Digital platforms: United Cargo capacity is available through CargoAi, cargo.one, for freight forwarders

United Cargo's position in the North American air freight market is built on the density and frequency of the United Airlines passenger network. The carrier processes roughly 4,500 flights per day across its system, with seven major hub airports spread across the continental United States. This network structure gives United Cargo one of the highest domestic flight frequencies among U.S. air freight providers, making it a preferred option for businesses requiring regular, consistent air freight movement between American cities and connections to major international markets.

Which countries does United Airlines Cargo deliver to?

United Cargo's domestic network is built around seven major hub airports distributed across the continental United States. On the West Coast, Los Angeles and San Francisco serve as gateway hubs for trans-Pacific cargo flows and West Coast commerce. In the American heartland Chicago O'Hare, Denver, and Houston form a central corridor for domestic distribution. On the East Coast, Newark Liberty International Airport and Washington Dulles International Airport handle high-volume freight flows to and from the northeastern United States. Together these seven hubs process the bulk of United Cargo's domestic volume, with spokes extending to more than 100 domestic station locations served daily.

Internationally, United Cargo's own flight network reaches more than 339 airports across approximately 50 countries, covering major freight markets in Europe, Latin America, Asia-Pacific, and the Middle East. The carrier's transatlantic coverage is significantly extended by its joint venture with Lufthansa Cargo, which provides additional capacity, co-located facilities, and integrated booking options between U.S. and European destinations. For markets beyond United's own network, a worldwide interline partnership program extends reach through cargo-transfer and code-sharing agreements with other airlines, covering virtually all major commercial freight markets worldwide.

• United States domestic: More than 100 station locations served daily, anchored by seven major hubs in Los Angeles, San Francisco, Chicago, Denver, Houston, Newark, and Washington Dulles
• Europe: Major markets served through United's own transatlantic flights and the Lufthansa Cargo joint venture, including Germany, United Kingdom, France, and the Netherlands among others
• Asia-Pacific: Japan, South Korea, Australia, China, Hong Kong, Singapore, and other major Asia-Pacific freight markets
• Latin America: Mexico, Brazil, Colombia, Peru, Argentina, and other Central and South American destinations
• Middle East: Key markets including the United Arab Emirates, with specific advance data submission requirements for shipments to, from, or through the UAE
• Global interline reach: Additional destinations worldwide through cargo-transfer and code-sharing agreements with interline partner airlines beyond United's own operated routes

A trucking network operated by United Cargo extends coverage beyond airport locations to regional and last-mile markets not directly served by flights. For certain routes and commodities, this trucking layer is built into the booking process, allowing shipments to originate from facilities that are not airports and similarly to reach final delivery points beyond the destination airport cargo terminal. The carrier also maintains dedicated pharmaceutical handling stations at a number of international locations, reflecting the significant volume of pharmaceutical and biopharma cargo moving through its network to global destinations.

What are the United Airlines Cargo services and delivery times?

United Cargo organizes its service portfolio into two core freight tiers and a series of specialty products designed for specific cargo types. The two baseline services, GEN and EXP, form the foundation for most general freight shipments, while specialty products cover temperature-sensitive pharmaceuticals, critical medical cargo, high-value freight, funeral shipments, and other specialized categories. All services operate on an airport-to-airport model, with booking available up to 14 days in advance for most service types.

• GEN (General Air Freight): The foundational, lower-cost tier for standard freight of any size within aircraft specifications. GEN provides access to the full United network plus interline connections, with a 14-day booking window and fixed drop-off and delivery times at each station. Unscreened cargo on GEN requires longer lead times before departure than screened cargo, and the service does not carry a boarding priority guarantee.
• EXP (Express Priority Freight): The elevated tier for shipments requiring faster movement, with boarding priority over all GEN freight even on high-demand routes. EXP offers shorter drop times and expedited transfer handling at connections. Acceptance windows before departure are tighter than GEN, and the service is available on both domestic and international routes, including through integrated trucking providers.
• QuickPak: United Cargo's end-to-end solution for smaller package shipments, available at 130 domestic stations and more than 100 international locations. QuickPak carries the highest boarding priority of any standard United Cargo service and is also available on United Express regional flights. Cremated remains under 45.4 kg on domestic routes are specifically channeled through this service.
• TempControl: Cold-chain service for temperature-sensitive cargo, built around compliance with IATA Temperature Control Regulations at more than 100 certified stations worldwide. Supports three temperature segments: controlled room temperature (15°C to 25°C), cool (2°C to 8°C), and frozen (0°C and below). A dedicated TempControl Tower provides 24-hour monitoring and proactive corrective measures including re-icing and lease management for temperature-controlled shipping units.
• LifeGuard: Dedicated service for lifesaving medical cargo including human tissues, organs, cell therapies, gene therapies, and clinical trial materials. Shipments receive the highest boarding priority on United and United Express flights, are hand-loaded and unloaded by specially trained staff, and are monitored through point-to-point barcode scans with optional GPS tracking. A 24-hour LifeGuard Desk provides continuous oversight, and advance booking is required at least two hours before departure.
• LifeGuardXL: Extension of the LifeGuard service for medical shipments exceeding 45.4 kg, with the same handling protocols, boarding priority, and dedicated desk oversight.
• UAPremium: The highest boarding priority service for critical shipments weighing more than 45.4 kg. Shipments are prioritized through the warehouse network from acceptance to recovery, with a dedicated UAPremium desk providing proactive monitoring. The service uses both widebody and narrowbody aircraft as well as trucking, with a 14-day advance booking window.
• UASecure: Elevated safeguards for high-value or sensitive cargo, including restricted access, monitored handling, chain-of-custody protocols, and secure vault and cage storage at stations. Intended for shipments with declared valuation exceeding $25,000, with priority boarding and around-the-clock monitoring across the worldwide network.
• TrustUA: Dedicated service for transporting casketed and cremated human remains with care and dignity. Shipments are proactively monitored throughout transit, and airport-to-airport connections are available through interline partners. Military honors including water cannon salutes, escort, and honor guard can be coordinated. Shipments of 226.8 kg or more require advance notification and approval.

Delivery times across United Cargo's network depend on flight schedules between origin and destination airports rather than fixed door-to-door windows typical of parcel carriers. Within the United States, the frequency of up to 4,500 daily flights across the system, including up to 750 departures daily from Chicago O'Hare during peak periods, allows same-day and next-day connections between most major domestic markets. For EXP shipments, the boarding priority guarantee reduces the risk of a shipment being held over to a later flight when capacity is tight on a given route.

For the most time-critical services, domestic acceptance and recovery windows are precisely defined. LifeGuard shipments can be accepted as close as 45 minutes before departure and are available for recovery as quickly as 45 minutes after landing. UAPremium operates on a 120-minute acceptance window at hub airports and a 120-minute domestic recovery time after arrival. For international shipments on EXP and UAPremium, gateway locations require a 180-minute check-in window before departure, with a 180-minute recovery window after landing. GEN international shipments require a 240-minute recovery window after arrival.

What are the United Airlines Cargo rates and maximum dimensions accepted?

United Cargo's pricing follows standard air freight principles. Rates are calculated per kilogram or per pound and vary based on the origin-destination pair, the selected service tier, shipment specifications, and any applicable surcharges or accessorial fees. A separate accessorial fee schedule is published specifically for U.S. and Puerto Rico routes. For domestic rate queries, United Cargo's online booking platform serves registered users, and freight forwarders can also access rates through the digital partner platforms CargoAi, cargo.one.

A core pricing concept at United Cargo is the distinction between actual weight and dimensional weight. Actual weight is the true physical weight of the shipment. Dimensional weight, sometimes called volumetric weight, is calculated from the shipment's length, width, and height divided by a standard dimensional factor. United Cargo charges based on whichever figure is greater, following standard IATA air freight practice. This means a large but light shipment may be rated on its dimensional weight rather than its actual mass, which is an important consideration when estimating costs for bulky goods.

• Weight and size limits for standard services: No fixed maximum, within aircraft specifications. The upper limit is determined by the physical constraints of the aircraft type assigned to the shipment.
• Widebody aircraft (767, 777, 787): Accept LD containers and pallets with very large payloads. The Boeing 777-300ER carries approximately 153,0 kg of cargo per flight.
• Narrowbody aircraft (737, A320 series): Bulk cargo is limited by door-opening dimensions. Individual piece weight limit of approximately 158.8 kg per piece on Boeing 737 variants and approximately 149.7 kg per piece on Airbus A319, A320, and A321.
• United Express regional jets: Accept only QuickPak and LifeGuard shipments under 45.4 kg, with no capacity for heavier or bulk freight.
• Pricing basis: Greater of actual weight or dimensional (volumetric) weight, following IATA air freight standards.
• Commodity codes: SCR codes following IATA standards are used to apply appropriate pricing categories to different freight types.
• Special cargo pricing: Live animals, dangerous goods, funeral shipments, and temperature-controlled perishables require direct contact with United Cargo for customized pricing rather than reliance on standard rate sheets.

For international rate inquiries, customers contact United Cargo's regional sales offices, whose locations are listed on the carrier's contact page. For allotment customers managing recurring freight reservations through the UC360 booking platform, rates and capacity blocks are negotiated in advance and must be reconfirmed approximately 24 hours before each departure. Customers who use digital partner platforms for booking receive rate information directly within those systems at the point of inquiry.

What are the United Airlines Cargo delivery options?

United Cargo is an airport-to-airport air freight carrier, not a door-to-door parcel courier. The standard model requires a shipper to deliver cargo to an origin airport freight facility and the consignee to collect the shipment from the destination airport freight facility within the applicable recovery window after the flight arrives. Recovery windows vary by service and route type. For most domestic premium services, cargo is available for collection within 120 minutes of landing. For international arrivals, the window extends to 180 minutes for premium services and 240 minutes for standard GEN freight.

• Airport-to-airport delivery: The standard model for all United Cargo services. The shipper delivers to the origin freight station, and the consignee collects from the destination freight station within the applicable recovery window after flight arrival.
• Integrated trucking network: United Cargo operates a trucking extension for select routes and commodities, enabling pick-up from origin facilities that are not airports and delivery from destination airports to final points in the surrounding region.
• Booking window: Up to 14 days in advance for most services, including GEN, EXP, QuickPak, and specialty products.
• Known Shipper requirement: Direct customers must hold Known Shipper status, which requires a TSA-approved site inspection, or be registered as an Indirect Air Carrier with the TSA. This limits direct access primarily to businesses and freight forwarders rather than individual consumers.
• Allotment system: Recurring customers can reserve blocks of capacity in advance through the UC360 booking platform, with allotments to be reconfirmed approximately 24 hours before each departure.
• QuickPak on United Express: The QuickPak service extends to United Express regional flights, reaching smaller markets beyond the main hub network that are not accessible through the primary fleet.

For customers who cannot collect shipments directly from airport freight terminals, the integrated trucking layer provides an extension of the air freight reach into regional markets. This option is built into the booking process for applicable routes, rather than being arranged as a separate third-party service. For the highest-priority specialty services such as LifeGuard and UAPremium, dedicated handling desks coordinate the specific logistics of acceptance, hand-loading, and recovery beyond the standard freight station process.

What should I do if my United Airlines Cargo parcel is lost or damaged?

United Cargo maintains a formal claims process for loss, damage, or delay. Claims may be submitted by the shipper, the consignee, or an authorized agent. The carrier enforces strict filing deadlines that differ depending on the type of claim, and missing these deadlines can affect the resolution of the claim. Three submission pathways are available through United Cargo's customer portal, covering initial claims, advance notices of intent, and status tracking for claims already in progress.

• Damage claims: Must be filed within 14 days from the date the cargo was received by the consignee.
• Delay claims: Must be filed within 21 days from the date of receipt of cargo. The delay must be supported by a specific date or event demonstrating that the delivery occurred late.
• Non-delivery (loss) claims: Must be filed within 120 days from the date the air waybill was issued, or within 120 days from the date the cargo was received for transportation if no air waybill was issued.
• Notice of Intent to Claim: If the 14-day damage deadline cannot be met a Notice of Intent to Claim can be filed through the portal to extend the timeframe before submitting the formal claim documentation.
• Processing time: A formal claim typically takes 60 to 90 days to process after submission.
• Declared value: For shipments of unusually high value, customers can declare a higher value on the air waybill to obtain coverage beyond the standard liability limits in the event of loss or damage.

The customer portal provides three distinct submission options. The first is to file a formal claim once all required documentation is assembled. The second is to file a Notice of Intent, used when a damage event has been identified but the full claim cannot be ready within the standard 14-day window. The third is a status check function that allows claimants to follow the progress of an active claim using a claim reference number. Customers are advised to review United Cargo's official tariff and applicable local cargo rules for the full schedule of liability limitations relevant to their shipment type and route.

For urgent assistance related to a damaged or missing shipment, United Cargo's general cargo support line in the United States is 1-800-UA-CARGO. Specialty services have their own dedicated contact points, including a separate line for LifeGuard medical cargo, a dedicated desk for UAPremium shipments, and a distinct contact channel for TrustUA funeral cargo. Air Waybill allocation requests are handled through a separate dedicated contact as well, distinct from the general claims and customer service desk.

Does United Airlines Cargo handle international shipments and customs formalities?

United Cargo operates a fully international air freight service, with the carrier's own flights reaching more than 339 airports across approximately 50 countries. Combined with the Lufthansa Cargo joint venture for transatlantic routes and a worldwide interline partner program, the effective international reach of the network extends to virtually all major commercial freight markets. On transatlantic routes specifically, the joint venture provides additional capacity, co-located facilities, and integrated booking that go well beyond what United's own flight schedule alone would offer.

A critical point for international shippers is that United Cargo does not provide customs clearance services. According to the carrier's rules and regulations, customs clearance and all related formalities must be arranged independently by the shipper or consignee. This means international shippers must engage a licensed customs broker or freight forwarder to handle import and export documentation, duties, taxes, and inspections at ports of entry. USDA inspections and Fish and Wildlife Service inspections for qualifying cargo occur at U.S. entry ports and are the responsibility of the consignee to arrange separately from the freight booking.

International shipments are governed by TACT rules, with United's specific exceptions documented in TACT rules section 8.3. Shippers must provide complete and accurate commodity descriptions on the air waybill or an attached manifest, in compliance with U.S. Customs and Border Protection requirements. Descriptions such as "gift," "daily necessities," "accessories," "parts," and "consolidated" are specifically flagged by CBP as unacceptable and may result in holds or delays at customs. The European Union's Import Control System 2, which took effect for air freight from March 2023, requires advance information for shipments traveling to or through the EU, Switzerland Norway, and Northern Ireland.

The UAE's National Advance Information Center requirements, effective from February 2024, require 6-digit Harmonized System commodity codes for all air freight moving to, from, or through the UAE. Wood packaging materials used on international shipments must comply with USDA treatment and marking requirements under international phytosanitary standards. Hazardous materials for international shipments must comply with IATA Dangerous Goods Regulations throughout the journey. United Cargo also explicitly restricts the transport of certain wildlife trophies, including those of lion, buffalo, elephant, leopard, and rhinoceros, regardless of accompanying documentation.

Understanding tracking statuses

When tracking a United Cargo shipment, the Air Waybill number is the primary reference. All United Cargo shipments are assigned an 11-digit AWB number, the first three digits of which are 016, the official IATA prefix for United Airlines. For tracking purposes, only the last 8 digits of the AWB number need to be entered on the United Cargo tracking tool. Tracking remains active from the time the shipment is tendered through 24 hours after delivery. Customs status is visible through a dedicated accordion section on the tracking page, and the United Airlines flight status tool can be consulted for real-time departure and arrival updates related to the specific flight carrying a shipment.

At each milestone in a shipment's journey, the tracking system generates a status update reflecting the current stage in the handling process. GPS-approved tracking devices can be attached to shipments for enhanced in-transit location visibility on both GEN and specialty services. LifeGuard shipments feature point-to-point barcode scans at each handling event plus optional GPS. UAPremium and TempControl services include continuous monitoring with proactive status checks managed by their respective dedicated desks. The table below lists the main statuses and their meanings.
