If you want to alter the the flight on both ends, arriving early and leaving later, assuming you make the deviations at the same time, does Regent charge one air deviation fee or two?

Regent will only charge one air deviation fee.

Yes - our experience has been that it is a flat fee for the initial deviation, regardless of whether it affects only outbound or both inbound and outbound. (Once upon a time, they would do a deviation fee for just one leg of the trip that was like half the cost of the 2 way deviation, but they don't do that anymore - it's either all or nothing!).

Be advised that if you make an initial deviation and pay the fee, and decide to do something different later on, you will have to pay an additional deviation fee (just like you have to do with airline change fees). This happened to us on our cruise last spring from Mumbai to Rome.

Thanks for all the info.

I read that info first before posting. Lots of information on your other pages that I have also read.

Well I just went back and added that new information on "one way flights" and also covered multiple air deviation requests at the same time for the same $150.

I am so glad you posted keeping all this information up to date and in full details is not easy at times.

THANKS
