Stand-by Airfare

The answer is that as long as you have the renter's last name (yours in this case) and the confirmation number provided at the time of the completion of the original reservation, you should not have a problem as long as there are cars available.  You should contact Budget or any car rental company if you are going to be early or late in picking up your rental car.

If you are changing to another set of dates rather than hour of the same day, the rates could be different. Weekend vs weekday rates.
