We normally drive to Florida (from North Carolina) for cruises but I found a good fare on Jet Blue Airline and we decided to give them a try. It turned out to be a great move as the flights were great. We had on-time departures and the only delay was a landing delay in Ft Lauderdale. The plane had 2 seats each side of the isle and plenty of leg room. The served soft drinks and unlimited snacks; that very different from other airlines.
After retrieving our luggage we took a taxi to the port. Although we had priority boarding because we are Elite members of the Captain's Club, we went through a regular check-in line and were on the ship in less than 30 minutes. The cruise line had a check-in line for each floor and one for suites. There were really no lines, just a couple people at each counter.
We were greeted when we boarded with a glass of champagne and since cabins were ready we went straight there to check it out and drop carry-ons. The cabin doors are very unusual because they open out into the corridors rather than inward. But since the cabin entryways are recessed you don't have to worry about hitting someone with a door when you exit, unless its the persons in the cabin next door to you.
