Yes, only budget. And not in the SAS confirmation mail, not on the budget Manage Reservation website, only in confirmation mail sent from the budget.com Manage Reservation website.

I went to get the car from SNA Avis today. The app was constantly crashing (maybe Friday 5.30 PM too many people try to access the system at once?..) while waiting at the baggage carousel and when it did provide me options, they were mostly smaller cars in lower (F reserved) groups. I was afraid there would not be many cars available at all or that it would be very busy.
However when I went to the preferred desk I was assisted immediately and given two options, Honda CRV or Toyota RAV4. I picked one, showed my European, non-Danish license and the receipt showed a USD price so I guess my contract is USD now.

Happy with 8 days rental for less than $200
