Received a D100 and & D300 by Fed Ex, may be du to the fact that I am in Europe (I did not pay anything for the 'overnight' delivery.
Just for your information, the coupon is valid one year, for only US flights, but includes CANADA and ALASKA. That might be interesting.
I was not targeted for this promotion, I just 'self-targeted' me, and it works.
Thanks a lot for those nice advices. Bonne Annee a tous (Happy year to everybody).
