So I do a search on the ITA Matrix site and then... what? It seems impossible to get these fares for real. Say, I searched for a trip, it gives me an itin with Turkish and American Airlines and those are not even in the same alliance so booking on the Turkish Airlines site is not really feasible... and it's actually two fares, saying:
Fare 1: Carrier TK SN2PX ODS to SFO (rules)
Passenger type ADT, round trip fare, booking code S, N
Covers ODS-IST (Economy), IST-LAX (Economy), LAX-SFO (Economy)
How is an ODS-IST-LAX-SFO trip a "round trip fare"?
Same for going back:
Passenger type ADT, round trip fare, booking code G
Covers ORD-IST (Economy), IST-ODS (Economy)
Again, ORD-IST-ODS is hardly a round trip fare... a couple years ago I did try the "bring this code to the agent" and even that didn't work
