I have been told that one of their major problems is related to Selects who try and book after signing into the Select area. The other is when someone has a defaulted discount code from a renewable membership club.If , for instance, your default code is from Costco or AAA, after a set time (generally a year) the computer rejects you because it doesn't know if you are still a member. Sounds crazy,but this is their explaination. Last week, I was able to book on-line for the first time since the new website was up. Avis manually redid my profile with the "famous "D002807" code as my default.I will book again today and see if all is still okay.
