If the auction hasn't opened you may change the value of your bid. To do this you just need to place a new bid with your amended bid amount/quantity. This will take the place of any previous bid once it has been confirmed in the app.
Remember bids aren't able to go lower than the reserve price.
Retracting a bid
Placed a bid in error? No longer travelling? No longer want to upgrade?
Auction rules are that once a bid is placed you're committed to that auction and your bid can't be removed. While we would never break a rule, we are happy to bend them from time to time. If the auction isn't live you may still be able to remove your bid by:
iOS users can follow the process outlined here: iOS: How to remove a trip. Following this will remove the trip from your account, as well as the bid.
Android users should write to email@example.com and one of our team will be able to help.
Once you place a bid, you agree to pay for an upgrade up to the value of your bid if you win. You cannot retract or cancel your bid at this stage.
