I found an awesome AA fare published from KTM (Kathmandu) to NYC which allows travel on KA and then AA via DFW. It books into the below buckets for each flight:-
KTM-HKG via KA - I Class
HKG-DFW via AA - R class
DFW -NYC via AA - J class
Now the ticket can be issued on JL or AA stock so If i can find an agent to issue it on JL stock would it post using the "special fare chart" or do they somehow share the fare info to calculate it with the fare method? The EQM difference would be in the of 3k betwen the methods.
