I booked a RT non-stop award flight through AA on LY (LAX to TLV). My understanding is that if I want to keep origin/destination the same and change the flight to go through JFK so that I am using both AA (LAX to JFK) and LY (JFK-TLV) I will need to pay the milage redeposit fee because I am changing carriers.
does anyone know if this is correct?
TIA
