Currently have BKK-FRA-MUC-YYZ booked.
Who thinks I should add YYZ-NYC today before the change, in the hopes that after I fly BKK-FRA, the rep will change me to FRA-NYC without a reprice?
(Essentially, If I add YYZ-NYC, I've made it so it won't change O/D after I arrive in FRA if the rep is inclined to just change it.)
