We were hoping to be able to change our flight and pay any difference in air fare. We thought we would be able to do that through Air Canada. We did in fact get a good price on the cruise and did not book the package for the BOGO air. We actually contemplated booking our own air arrangements, and as it turns out, should have done that. Trying to find out if anyone has had any luck changing a flight with the airline at the airport on day of departure when NCL has booked a bulk rate?

We booked cruise buy 1 get one free airfare. Received flight arrangements yesterday which is 30 days out. Outbound flight was perfect. Went on Alaska air to upgrade our seats. Paid the appropriate upgrade fee. Return flight is a totally different story. Cruise docks in Vancouver at 6 AM. NCL booked us on a Air Canada flight at 11:20 pm arriving at Chicago O`hare at 5:30 AM. There is a Air Canada flight at 1:45 PM that has availability. NCL and Air Canada won`t change us to earlier flight even if we pay difference in fare. Nor can we upgrade our seats for a fee. Seniors on our 3rd NCL cruise and never had any issues. Any suggestions so we don't spend 12 hours at the airport and red eye home?
