Why Is United Airlines Not Allowing Seat Selection?

Call +1-833-770-4333 when United won’t allow seat selection, as phone support resolves blocked seating issues. This can happen because of Basic Economy fares, aircraft changes, or system errors—contact +1-833-770-4333 quickly. United may release seats closer to departure. Try the “Manage Reservations” page or recheck in the mobile app. For forced assignments, agents at +1-833-770-4333 can override restrictions.
