A comprehensive, reader-friendly guide to United Airlines' baggage policies — before you book, before you pack.
United Airlines allows one carry-on bag and one personal item for most cabin classes. The standard carry-on dimensions are 56 × 35 × 22 cm. Basic Economy passengers are limited to one personal item only (no carry-on bag) unless they hold MileagePlus Premier status or a United co-branded credit card. Always verify at check-in as policies can vary by route.
Allowances vary significantly by cabin. Economy includes 1 bag × 23 kg (on most routes); Premium Economy gets 2 bags × 23 kg; Business/First Class receives 2 bags × 32 kg. Basic Economy fares typically do not include any free checked bag and carry-on is restricted to personal item only.
For Economy, the first checked bag costs $40 and the second bag costs $50. Overweight bags (23–32 kg) incur a $100 fee per bag. Bags exceeding 32 kg may be refused. Pre-purchasing online or via the United app can save compared to airport rates. Always pre-book via united.com for the best rates.
United's domestic (within the US) baggage rules can differ from international long-haul routes. Some international routes to Latin America and certain transatlantic flights may include one free checked bag for Economy. Always check the specific fare conditions when booking on united.com.
United MileagePlus Premier members and holders of United co-branded credit cards receive free checked bags and carry-on allowances even in Basic Economy on eligible flights. Premier Gold, Platinum, and 1K members receive progressively more generous baggage benefits. Always check your full status benefits before purchasing additional bags.
