just did this 2 weeks ago! my original reservations was TLV-FRA-JFK, i wait-listed the direct TLV-EWR flight and got confirmed around 24hrs. before flying. on the return i wasn't so lucky as every flight was booked solid(business class) so i ended up flying from JFK-MUN-TLV,the stopover was only a little over an hour,not bad at all. the flight experience was ok,other than the kosher meals which were pretty subpar. it was 115,000 co miles roundtrip
