Hi there, we only use Avis for our car rental needs in the US because of their tie-up with British Airways (who have their own AWD codes and are readily searchable on Google). On all of our rentals, which have been major airports, we have received notification of our allocated vehicle by text/email/app prior to landing meaning that you can bypass the desk and jump in the vehicle an go. I've only had to show my drivers licence at the exit booth from the lot, and I've never been asked to demonstrate that I'm a British Airways passenger (and therefore eligible to use their AWD). Also, as long as your credit card is registered in your Preferred profile, I don't believe you'll ever have your card swiped either as it is pre-authorised.
