Got an email saying celebrity will guarantee the choice air flight is the lowest price available with a 110% refund of any difference found. Basically booking cruise and flight will save time, effort, be simpler, etc. Plus you can choose the flights you like if say you prefer to come in the day before, be first on board, or arrive late.
Here's a copy:
