I've rented a car twice in my life, and I just paid a TA to do it for me. I know that the "Need help?" thread barely gets responses, and I don't mind doing the legwork myself. My problem is that I have no idea where to start.
I can read the wikis of the main companys' master threads, but how does one go about deciding who to rent from and which codes will work best for their specific situation? When I want to fly somewhere, I can use ITA to determine which airlines fly my route and then figure out which partners can book that route for the cheapest points. Any ways to knock down the car rental options, so it's somewhat less daunting to start searching? Or does everyone here search through every major company's site and try all the codes till they find with company/code will be cheapest?
