The average cruise lasts a lot longer than the average flight. Even if you only consider time between ports, two days is common and more isn't unusual. Even a moderate-size cruise ship holds more passengers than a packed all-economy A380, with large ones holding several thousand. For both those reasons, the odds of someone dying on a cruise are way higher than the odds of someone dying on a flight even before you consider demographics.
