Plans change, and that's ok. If you sent a Host a trip change request for a confirmed reservation, you can withdraw the request and keep the original reservation.
To withdraw a trip change request:
Go to Trips and click the trip that you want to change
Under Changes pending, click View
Click Cancel To check the status of your reservation, go to Trips, click or tap Show more trip plans, and then Show details. You can also check your Inbox for messages from your Host.
