About a year ago we flew into Burbank Airport in California. We had never flown into Burbank before, and assumed that we would rent a car at the airport to drive during our stay and turn it back in when we left. It turned out that Enterprise, a rental company that we have used often with no problem, required a $350 deposit or they wouldn't rent to us. They had never required that of us before, after we had rented a couple of times, and we had rented in Cali a number of times. This really put us out! Was it because we were coming in through Burbank, or some other reason? Thanks for your answer.
