Somebody asked about those without passports. I suspect the passport-less will be on the charters, to make it easier for CBP. Alternatively, I suspect those with passports that need to fly further than MCO will be given priority for the scheduled flights.
Sounds like the situation onboard since they made the fly home announcement has been quite fun.
Also, Carnival Legend is now having propulsion problems and limping back to Tampa. Definitely time for a review of maintenance procedures.
