I have booked a ticket from PIT-IAD-SFO in the A4BA3S fare basis. Since the first segment (PIT-IAD) is on UAX, the Booking Code is B, but the underlying fare basis is stil A4BA3S. Will I receive credit for the A (first) class of service bonus or only the B coach booking code on the UAX flight?</font>
I've booked paid F tickets that include United Express segments.
You do
not get the class-of-service bonus miles for the United Express flights.
This definitely varies by airline, though. CO does give class-of-service bonus miles for Continental Express flights.
