I do a one day rental each week at a HLE. I use my Amex Plat CDP and every time the booking rate is different from the confirmation rate, some times significantly. Yesterday my daily rate in my booking confirmation was about $31 however when I picked up the car it printed out over $50, the entire difference was in the daily rate. They always adjust the rate down to the confirmed amount when I return it but that is a pain for both me and them. I have been working through this for months with the agent and we look at the computer together before he clicks on the booking and it reflects the correct rate then after he clicks the booking it always bumps it up. Has anyone else experienced this or know what it might be. I do cancel and rebook regularly when rates drop, and they are always working off the only live reservation out there not one of the cancelled ones.
