Modify or Cancel a Car Rental Reservation

Reservations can be modified or cancelled online.

Alamo's Cancellation Policy:

• Free Cancellations:
  Cancellations are accepted at anytime where a form of payment, like a credit or debit card, is not provided to secure the rental reservation.
  
  
• Guaranteed Reservations:
  Cancellations are accepted up to one calendar day before reservation date.
  Reservations canceled more than 24 hours before the pick up time are free. If the reservation is canceled within 24 hours of the pick up or if the reservation is not used, a $50 cancellation fee will apply.
  
  
• Pay Now Reservation Cancellation Fee:
  Please note that you must present the card you prepay with at the time of rental pick-up.
  If a Pay Now reservation is canceled more than 24 hours before the pick up time, a $50 cancellation fee will be assessed. If a Pay Now reservation is canceled within 24 hours of the pick up or is not picked up at all, a $100 no-show fee will be assessed. Any optional insurance or CDW product selected at the time of reservation may be canceled at the counter at the time of rental without incurring a cancellation fee.
  
  
• Accelerated Check-In:
  In the case of using Accelerated Check-In in conjunction with Pay Now, a cancellation fee may be applied. Otherwise, there is not a cancellation fee associated with Accelerated Check-In.
