On the Trips page, find your trip and click the dots menu in the upper right corner. Choose "Manage Flights" or "Manage Hotels" to make changes.
A new menu will appear that allows you to update your booking. Select the trip service you'd like to update, and then choose either "Cancel Booking" or "Other." If you select Other, please provide as much detail as possible about the change. When finished, click the "Next" button at the bottom of the screen.
