Different fare classes, same ticket, possible?
I'm in the process of booking flights ORD-ORK for my sister and want to apply GPU (SWU) to the ORD-LHR portion. Is it possible to have the ORD-LHR booked in W and the LHR-ORK booked in K? (to possibly save a few $)
Sorry if this is common knowledge, or already explained, I tried searching several different versions of the keywords without success.
Thanks!
