My sister and I arrived late from Negril back in November. When the woman at the counter told us we could not get a flight out for anothe 3 days, we just looked at eachother and smiled. We sure weren't gonna cry about it! I would say 3 hours just to be safe. Yes, that last day sucks. Hard to get your last swim in before that airport ride. Earlier this month when we (3 sisters ) were there for a weekend, we were pretty high trying to distribute weight in bags before check in lol.
