I totally disagree. We have booked Air2Sea and Flights by Celebrity and it has worked out well for us. We only do it when it is an International flight. We had snow and were unable to fly out last year in February to Buenos Aires. Flights By Celebrity was great and rebooked us and made sure that we made it to our cruise on time. If I would have booked it myself, they wouldn’t have cared about us making the cruise and this is why it is important to me to use them. Weather happens and they were accommodating. I also like to use them because I can book early, make changes, make payment when final cruise payment is due and if I cancel my cruise, I can cancel my flight.
