# How to determine if a flight change has occurred?

**You can refer to the following steps to determine if a flight change has occurred.**

**Step1**: Check whether you have received a flight change notification email. If you have, then a flight change has occurred. If not, then proceed to the next step.

Check Path： ATRIP -> Bookings -> My Bookings -> Booking Details -> Email List

**Step 2**: Check the airline's MMB system and verify if there is any flight change information displayed. If there is, then a flight change has occurred. If not, then proceed to the next step.

**Step 3**: Review the airline's Flight Status page:

If the flight can be located and the status is "cancelled", then a flight change has occurred.

If the flight can be located and the status is "normal", then there has been no flight change.

If the flight cannot be located, and departure is not imminent, then the occurrence of a flight change cannot be confirmed.
