It never hurts to call the airline directly. I have done just so for tix booked through RSSC for other cruises.

Not to get you all hot and bothered, but I think I received seating for my PG flights before final payment.

Sue, whatever happens, it is not the end of the world. It is a very comfortable plane. You will each have your own screen with games, movies on demand etc. There is nothing to "see" on the way over.

Adults are served "adult" beverages. As a pilot, you should just chill and enjoy, after all, you are on your way to paradise.
