I can tell you exactly what they will do! Nothing.
Last July, we took a Baltic cruise and took advantage of the BOGO deal. Our flight was late leaving the US and then our flight to Copenhagen was cancelled. We arrived in Denmark about 30 minutes too late to be able to make the shuttle to the port.
We assumed NCL would help us get to the next port. Come to find out, they will not. We were told that it would be up to us to get to our next port in Germany and on our own dime. A 4-hour train ride and $400 later that we made it to Germany and got on the ship the next morning.
I will give NCL credit for how they treated us once we got on the ship as we also did not have any luggage (thank you, Air Canada). They gave us free, expedited laundry to wash what we had and the clothes we ended up buying as our luggage never made it to us while on the cruise. They also gave us a toiletry kit to get us through.
All this to say, NCL's BOGO air deal is a good deal...until it's not. We are booked for March 2023 and chose to try it again. However, we did a one-day deviation to provide a buffer in case of delays and we'll be carrying on a small bag of "just in case" clothes 🙂
