A little follow up. I did my reservation and dropped it off yesterday at Chattanooga. Changed my mind on ending in Indiana before my trip started. I used WestJet code 3715794. Every other code came back well over $1,000 for the 8 day rental and I paid about $300 with it. I was really impressed with the price. Selection at STL was not great but I did end up with a Hyundai Sante Fe from the executive aisle. Was not my first choice but it worked out.

It was unlimited mileage but funny they did not even look at my mileage. They just put in 75 miles above what I left at. I really drove about 850 miles. Hopefully they update that in the computer before the next person takes the vehicle.
