Flying United Airlines: what to know
Bags: where the fare grows
The ticket price is only the start on United Airlines. A first checked bag runs $45–$50 (cheaper when prepaid online), and a second is $55–$60. Carry-on: Free on most fares — Basic Economy allows only a personal item on many routes. If you know you'll check a bag, tell us when you enquire — we'll price the ticket with bags included, so the number you approve is the number you pay.
Changes and cancellations
No change fee on standard Economy and above (US flights); Basic Economy can't be changed. Cancellation: Free within 24 hours of booking; after that, standard fares cancel to flight credit. The practical takeaway: if your plans might move, the cheapest fare class is often the most expensive mistake. Ask us to price a flexible fare alongside the basic one — sometimes the difference is a few dollars, and it buys you real options.
Where United Airlines is strongest
United Airlines routes its network through Chicago (ORD), Denver (DEN), Houston (IAH) and more. Fares are usually sharpest where the airline flies nonstop and often, so hub routes are where deals show up first. Routes our travelers book most: New York to Miami, New York to Boston and New York to Denver. You can also browse today's live deals across every airline we track.
- Pay for checked bags in advance when you can — the airport counter is rarely the cheapest moment.
- The 24-hour rule protects you: cancel within 24 hours of booking for a full refund on tickets bought a week or more before departure.
- Set a fare alert for your route — United Airlines fares on popular routes move several times a week.
