No fastbreak points if credit card not accepted
In all my years of collecting points from different airlines/hotels/rental car agencies, I just came across a new oddity. When reserving a car for Curacao, I entered my Fastbreak number as part of the reservation. When the reservation was confirmed, the site notified me they could not associate my Fastbreak number with my reservation and to call Budget directly. The Budget customer service rep (in Mexico) told me that since I only had an Amex card associated with my Fastbreak account, they could not associate my Fastbreak number with that reservation. I would have to give her a MC or Visa number in order to add my Fastbreak number to the reservation.
Is this normal? I've never had my rewards points dependent on the credit card I used.
