Therefore, if you have to go for a**************** flight change, choose a different flight. On most fare types, United doesn’t charge a flight change fee. Moreover, the airline lets you change your booking as many times as you want. You don’t have to pay for even multiple flight changes! However, pay the fare difference between the new and original
flights, if required. So, if you have to change your**************** booking, go ahead. But keep the guidelines in mind, and you will have a smooth experience.
