My family flew to Tampa, FL airport during the week between Christmas, 2013 and New Years. We had booked airline tickets and a rental car from Ace Rent a Car for one week, both through Cheapoair. When we arrived in Florida and called the number provided for passenger pick-up, Ace said they had no car available then and to call back in one hour. One hour later, they still had no car and said to call back after 4 pm, 4 hours later. When asked if we were guaranteed a car at that time, they said no. This was despite having the reservation for over 2 months. I called Cheapoair, and they also called the rental car company and confirmed the information. He made it clear that we were on our own and that all we could expect in compensation was to be reimbursed our booking fee. They could clearly give a rip that they were not fulfilling the reservation and did absolutely nothing to help us in our predicament.
I WILL NEVER use Cheapoair or Ace rent a car and wouldn't have if I had done more diligence in checking out reviews. Any search or clearinghouse service should remove Cheapoair and Ace from their options.
