Have a question regarding using my credit card points to book a few days with National (2nd time doing so). Booked "intermediate" (midsize) using my C.C travel booking website. The first time I this was at a smaller airport location and was given a car in the class I reserved (premium) plus was rewarded credit for my rental. I called National so that they assign my club number to this rsvp but was told that since it was prepaid would not be able to do over the phone. Being that I am a member and booked midsize via a prepaid RSVP am I still eligible for AE/ES ?
