United Airlines has a cancellation policy that varies based on the type of ticket purchased and the circumstances surrounding the cancellation. Here's a general breakdown of their cancellation policies:If you purchased a non-refundable ticket, you can cancel your flight, but you won't receive a refund. However, you can typically apply the value of your ticket towards a future flight, minus any applicable fees. United charges a fee to change your flight or cancel it, and the remaining balance can be applied as credit towards a future flight.
