We originally had a flight departing from Orlando airport at 12:00, however there has been a schedule change and American Airlines have rebooked us on a flight departing at 11:28. This is our first cruise, and from my understanding to use the DCL onboard check in, your flight can not depart earlier than 11:30. Is this correct? Would they allow us to check in onboard even though it's 2 mins earlier? Has anyone else experienced this before?
