I tried replicating your steps and can’t figure out how to get the coupon to apply. On the payment screen my only option is to use a credit card. I see no mention of coupons even though they are showing up in my account.
We have the opposite problem of the OP. NCL Air has just booked us on an 11AM flight back to Toronto from Miami. What time will they let us off the ship? Will we be given any sort of priority to get off first given our flight time?
