If you’re running late, adjust your reservation’s end time in your account on the Avail app or our website. Car sharing relies on you to return the vehicle on time. This ensures that we can prepare the car for the next borrower or return the vehicle to the owner at the time they expect.                                               Because of this, some trips cannot be extended. If you’re unable to extend your trip and you return a vehicle more than 30 minutes late, you will usually incur a late fee. If you need to cut your trip short, you can change your end time in your account on the Avail app or our website. Since our rental periods are in 24-hour increments, we can only provide a partial refund if you return the car more than 24 hours early.
