booked with the same insurance claim code at Denver airport. One confused young man behind the counter who had to get his supervisor, who then said that they couldn't do it and started asking me similar questions about claim numbers, etc.
Based on that experience I could not recommend using the code unless you have the insurance claim to back it up...
Same deal here. Bunch of b.s. when I went to pick it up. I had printed out the page from rentalcarmomma.com and showed them. The agent then started a new rental for me at 3X the cost! Told her to take a long walk and went and rented elsewhere.
I'm not using that code in the future.
