Uber doesn't guarantee that a driver will accept your ride request. Your ride is confirmed once you receive your driver details. **Reserve trips made in advance are subject to a cancellation fee. You can cancel at no charge up to 60 minutes before your reservation pick-up time.
How long does Uber wait before Cancelling?
WHEN WILL YOU BE CHARGED A CANCELLATION FEE. Shared Rides: If you cancel more than 2 minutes after your UberX Share request has been accepted OR if your driver cancels after waiting at least 2 minutes at your pickup location.
