You can use the coupon with the AWD number. You will have to call reservations to use the AWD number if it isn't in your profile. If you book online, it will simply mean you will have to go to the counter to have your contract printed. You will have to go to the counter anyway to present the coupon so it doesn't matter where you book the reservation. The coupon is only valid for a 2 class upgrade with a maximum upgrade to a premium and IS BASED ON AVAILABILTY at time of pickup.
