Changing a United seat in the app
It also provides check-in, boarding-pass access, flight updates, and a way to communicate with an agent. Keep a seat change separate from a flight change. Start with the existing flight, compare the available seating options, and review any amount or restriction displayed before you confirm. The app’s ability to handle seat changes does not establish that every fare can move to every seat without a charge. After making a selection, check that the trip shows the intended seat for the correct traveler and flight. When the option you need is unavailable or the app cannot complete the request, use its agent communication option. Ask about the specific seat change rather than assuming a new flight booking is necessary.

Important unknowns
- Fare eligibility, seat fees and final change cutoff are not established by the app description.
- Live canonical owner and nearest-page content are UNKNOWN because the sitemap index could not be retrieved.
