Thanks, that is great information.
So, it looks like my best/only option is to route to either BKK or SIN.
Assuming there are 2 stopovers allowed, then I SHOULD be able to go JFK-LAX-ICN-(stop)-BKK-(turnaround)-BCN/MAD-FRA-JFK? If only one stopover, then I'd just have to get to BKK and have that as my first stop on the trip, right?
OT - I have EF and based on what I saw you post figured out how to get the MPM through the routing rules. Question - what airline's rules do you look for, the ticketing carrier or operating carrier (or are they all the same)?
