As said, the cruise lines do use bulk ticketing, and when you book air thru them, they only agree to get to your destination.I seriously doubt that the one change that you mentioned, the 2nd change in flights was Princess' fault, I would imagine that it is the airlines change, I've had this happen many times, cruise or no cruise.There are times however, when the cruise line flights are cheaper than you can get on your own.
