Important notes: United’s page does not list a static fee chart. It directs travelers to its fee calculator, since fees depend on where you travel and when you bought your ticket.
How We Check This Policy: We read size, weight, and fee-change details from United’s official Checked bags page. Because that page points to a calculator rather than a fixed price list, we cross-check typical domestic fees against reporting that quotes United directly, and we flag which figures are standard domestic prices versus route-specific. Always run your itinerary through the calculator before you fly.
Official United Checked Bag Policy Overview
According to United, the maximum united airlines checked bag size is 30″ × 20″ × 12″ (76 cm × 52 cm × 30 cm), or 62 total inches, including handles and wheels under the united checked bag policy.
The united checked bag weight limit depends on your cabin and your MileagePlus status. If the two give different limits, United goes by the one that is larger.
| Cabin | Maximum weight per bag |
|---|---|
| United Economy and Premium Economy | 50 lb (23 kg) |
| United Business, United First, United Polaris | 70 lb (32 kg) |
| MileagePlus status | Maximum weight per bag |

| Premier Silver, Gold, Platinum, 1K | 70 lb (32 kg) |
| Star Alliance Gold, in Business | 70 lb (32 kg) |
| Star Alliance Gold, in Economy | 50 lb (23 kg) |
United also notes that additional fees apply for extra checked bags or bags over the size and weight limits.
What Makes the United Policy Different
Several distinct factors make the United policy unique for travelers:
- Staged fee increases in 2026: United’s page notes fees rose for tickets purchased on or after April 3, 2026 for domestic flights and short-haul flights to Canada, Mexico, the Caribbean, and Latin America. Fees for many flights between the U.S. and Africa, Asia, Europe, and South America rose on or after May 12, 2026, while transpacific routes adjusted July 21, 2026.
- Purchase-date fee tiers: The fee depends on when you bought your ticket, meaning two travelers on the same flight can pay different rates.
- Status and cabin determine weight: The higher of the two limits applies, allowing a Premier member flying in standard Economy to check 70-pound bags.
- Prepay discount: Paying online at least 24 hours before departure saves $5 per bag on the domestic first and second bags.
- Bag drop shortcut: Travelers can register bags during online check-in and drop them off rapidly at a dedicated airport lane.
