From their terms and conditions:
13. Offer may not be used in conjunction with any other coupon, promotion or mileage offer, with the
exception of the Avis Flying Blue bonus miles for joining Avis Preferred.
If booked with the coupon , I am not sure if you still qualify for the Flying Blue promotion!! Moishy, Do you know?
I don't have a definitive answer one way or the other, though I wouldn't risk it, and here's why: as Chaikel pointed out, there have been issues with getting the miles automatically in the past, where human intervention was required to manually credit the miles. That being the case, even if the computer wouldn't notice the coupon due to a glitch, there's a possibility that a human - in full troubleshooting mode, reviewing your six contracts - will spot it, and
pasken that that's the reason for not getting the miles. And then you will be SOL.
