TWA cancelled their JFK to Rome route last year, and I had 4 bus tix (upgrades) booked. They couldn't get me into Rome within 2 days of when I needed, would only use 1 (or 2?) other airlines, and in coach. They offered me Milan (coach) and get to Rome on your own. A friend said that I'd get my seats, and I called a supervisor who thought I should. I did, a couple of days later. If they still flew to Tel Aviv, I'd suggest you fly there, but perhaps they fly somewhere nearby - unfortunately there's no perfect solution that's likely to be reached.
