While trying to book a flight TLV to NYC on a *A combo ticket of 3 different airline codeshares (something like LX, UA, OS - don't recall exactly) with Chase UR, she was warning me that it may not be worth it, because if I will want to make any change, I would need to pay a change fee to each of the 3 airlines
She must've never booked an int'l flight before....
Though I've actually hardly ever found any real competent reps in URs travel department.
