Schwartz man-LY - Welcome to FlyerTalk. Always nice to have a new TLV based member.
As far as coach, CO has sub-par 31" seat pitch. I'm not sure where LY stands there (32"?).
CO has interactive menues byt LY has better movies...
What I like the most about CO is the lack of Jewish Orthodox people flying. These can be a real pain at times (especially when in groups or when it's praying time).
