There are very few flights that will only be one stop, EL AL, Air Canada via YYZ, CO via EWR all with no availability.
Besides that availability is terrible all round.
So, on star alliance I've checked Continental, Austrian, Air Canada, US Airways, Spanair, Lot, Lufthansa, Swiss, Turkish, Brussels, non have availability.
The only flight out of TLV is on Aegean but then youre stuck in Athens.
OneWorld, British, Iberia, Malev etc. no availability...
Delta almost always has availability. True but its really expensive, you may as well fly Business (if it were available)
There are more but basically nothing feasible without at least 3 stops or a 10 hour overnight stopover.
The way back is not a problem...it just seems that everyone is leaving TLV that week...
