I must respectfully disagree with captplaystation, having experienced both the deep sea and the Loco life. Being home every night on a fixed roster, with the odd week here and there away is infinitely preferable to 3 months working a minimum of 10 hours a day, 7 days a week in some fairly rough weather. If you think the walk around in Poland in January is bad, try mooring ops at the top of the Baltic at the same time of year!
That's before my wife and family start coming into the equation. If flying is what you really want to do, go for it. But if you do, keep your CoC for the ships current as it means you always have an exit in your back pocket. Cruise ships are not as glamorous as you might think either - the pay is worse than cargo, you spend more at sea do you can't save as much, and 4 months doing the same one week cruise out of Miami or Fort Lauderdale would drive me utterly insane.
