Are different booking classes on the same trip allowed?
I read the EduGuide and searched but am having difficulty finding a definite answer.
On multi-segment flights, does each segment have to have availability in the same booking class (fare code) to be bookable?
In case the above isn't clear, here is the situation:
Looking at the fare buckets on ExpertFlyer, there is a roundtrip flight with one connection each way. The first segment has availability in a $400 fare basis (and a $700 fare basis) and the second segment only has availability in a $700 fare basis.
Can I pay less than $700 for this trip because the first segment has available seats in a cheaper booking class?
