United Airlines: common questions
Does United Airlines charge for checked bags?
On most economy fares the first checked bag costs about $40 each way (more at the airport). Premium Plus, Polaris Business and Polaris Business Flexible fares include at least one bag. We show the bag allowance for every fare before you book.
Can I bring a carry-on on United Airlines's cheapest fare?
Yes. United Airlines's Basic Economy fare includes a personal item and a full-size carry-on bag, but seat selection costs extra and the fare cannot be changed.
Can I change or cancel a United Airlines ticket?
Every booking on Air1 Tickets can be cancelled free within 24 hours (for flights 7+ days out). After that, Basic Economy fares cannot be changed, while Economy fares allow changes with no change fee (you pay any fare difference). Refundable fares return the full amount.
How do I check in for a United Airlines flight?
Check in online or in the United Airlines app from 24 hours before departure using the airline confirmation code on your Air1 Tickets e-ticket. Your Air1 reference is for managing the booking with us; the airline code (six characters) is what United Airlines needs.
