About a year ago, I booked a cash RT J ticket from ORD to Tel Aviv through AA (on USAir metal). When the TLV service was discontinued last fall, they called me and offered to rebook me, and they gave me a ticket on El Al, in first! Now, 6 months later, I called AA to ask about the flight....to make a long story short, they are now cancelling the ticket and offering a refund. Flight was supposed to leave in 2 weeks.

Do I have any recourse?
