El Al does offer PTVs on all 744s and 777s, but not on 762s.
LY Economy pitch is 32" in the 744 and 31"-32" in the 777.
Around April all 744s and 772s will offer the same;
The 744s would get new seats with in-seat phone, infligths games etc', on the other hand, the 777s would have a new seating cofiguration with 32"-33" pitch.
Also both types will get a new C/class and the 744 would get a new F/class, more info later...
As for your question between CO and LY, LY is different, it would be much more interesting and besides, by taking LY you can enjoy both the 744 and the 772.... think about that...
LY doesnt operate pax 742 anymore and the last flight between TLV and JFK/EWR with 742 was few days after 11SEP when there was need for extra capacity on that route...
Any other questions?
