Title says it all. I would like to do a TATL outbound in Premium Voyageur and return in Affaires, as the price for the latter is very attractive for my itinerary and date, but the website doesn't seem to permit mix-and-match of classes. Will AF book it this way for me over the phone? Or do you know of a booking website that allows you to select a different class of service in each direction?

I don't think it would work to book the whole RT in PV, then try to upgrade the return leg, as the fare class seems not to permit changes.

Thanks.
