I just rented from CLT and had a interesting experience. The shuttle bus took around 10 minutes from when I called the branch until it arrived at the terminal. The driver was friendly and agreeable. Just prior to arrival, he asked my name and radioed the station. I had reserved an ECAR and was handed a contract and keys as I walked in after a quick id check. I was told I was receiving an ICAR - Nissan Sentra with 20k miles on it. It was late so I did not inquire if there were any other options.

When I returned in the morning, there was only 1 employee at the branch handling rentals and returns. She paused a new rental customer halfway through to handle my return. She discovered that there never was an authorization taken on my credit card. Additionally, neither my Sixt Diamond Card number nor frequent flyer number were present on my reservation. As with LAS, this seems to be a persistent bug in US reservation system. I presented a different credit card for payment than what my profile contains, but apparently charges ended up on the card on my profile. Additionally, the location did not properly record the miles on return and apparently at pickup either. I did not drive over 1000 miles during my 10 hour rental period. Miles were under-recorded at return by 12 miles from the actual miles on the odometer.

The shuttle driver on the way back to CLT was friendly and likeable. The issues I encountered are minor compared to other posters', but still indicate that CLT is not operating at the service level of its competitors.
