I'm responding to MMKETEER regarding a backpack and carry-on. We just came back from 2 weeks on Hawaii land trips, and all but 2 planes out of 9 (getting there, back, and island hopping) would a backpack and carryon not cut it. If you're flying to the ship, obey these guidelines carefully, or you could be sorry in more than 1 way.
Domestic air-50 pounds and 60 inches to be safe (some are up to 62). $25 extra for 51-70 lbs.
International air-70 pounds and 60 inches. A combination of both domestic and international, they abide by the international. Over 70 pounds, $85. KEEP IN MIND THIS IS PER FLIGHT. FLYING 3 SEGMENTS, MULTIPLY BY 3.
We met someone that brought her "boogie board" with her. It only cost her $90 new, and they charged extra baggage, and $85 each way.
They don't let you combine weight under any circumstances.
We also fly out of Tampa, as we live about 1-1/2 hours North. Do what security says, and above all, don't talk back. Nothing is the same for the airports you go through. You'll need passports or ID and 3-4 points at 1 airport, and only need it checked once at another. Not knowing what we would encounter, always have it ready. Hope this is a little help to people that are flying with cruising.
