I have to say that the Regent deviation plan is very good. If you pay it, they allow you to see what flights are available in their system so you can choose your flight. A big plus. Oceania will let you pick flights for the deviation fee but you also must pay fare differences for the same flight per the TA working on our O cruise. A big plus to Regent on this aspect of air travel. We have ALWAYS been happy taking Regent's air packages.
