I've had no problems using points to book in the U.S., but am having problems using points for Europe.
No matter what I try (standard or anyday) fnothing works. I just get
"Promotion Coupon you've selected is not available for this rental either because that location isn't participating or some requirement for the offer hasn't been met."
I just tried for both Paris CDG, and Madrid MAD. First I tried 3200 standard rewards for one week green rental. I tried about 14 different weeks between April and Sep 2012, and then even into 2013 just to try. No matter what, I get that the PC could not be applied. When trying the 6400 Anyday rewards though I get the same message. When trying the 1800 Anyday reward for one free compact or intermediate on many different dates at either airport, I get the same message.
