On United Airlines in 2026, the easiest way to identify your fare type is to look at your Confirmation Email or the "Manage Trip" section of the United app. Basic Economy is clearly labeled and comes with several "Hard Restrictions" that regular Economy does not. Specifically, if you have Basic Economy, you cannot bring a full-size carry-on bag (except on trans-Atlantic flights), you are assigned a seat at check-in rather than choosing one, and you are in the last boarding group (Group 6). Your boarding pass will also feature a distinctive bold header or a "No Carry-on" icon. A high-value 2026 "pro-tip" is that if you have a United co-branded credit card or Premier status, some of these "Basic" restrictions (like the carry-on ban) are waived, but the ticket remains "non-changeable." If your ticket allows for a free "Economy Plus" upgrade at check-in or allows you to change your flight for a fee, you are definitely in standard Economy, not Basic.
