Return from Europe C Class service most of the times is a bad one...,
You need to "understand" the F/A... they came with the previous flight,
the help on cleaning the plane, and they need to serve you on the way back.
If its a nightly flight and there were delays, its even getting worse.
My last flight from paris to tel-aviv, the parser was looking sleepy
even before the take off...
I understand the F/A, I dont understand EL-AL, They should make sure
such things doesnt happen even if it means leaving an additional crew
to be fresh for the flight back - We pay good money for that.
(90% of my flights are in C)

Lounge:
EWR was always a pain, Even with the new one... I dont find comfortable,
This is why i like to fly from JFK... But EL-AL have a big problem... too many
Golds / PLs which dont fly business but still access the lounge (I have nothing
against it, i do this as well sometimes).
The issue is that you end up with a small lounge (well it also soemtimes in KD in TLV) which is overloaded with people, My last flight from paris, they went
out of food! no place to seat and so on.
Its impossible to have 24 seats in business and a lounge with 60+ people
when the lounge is built for ~50

As for F class, The service i got was always very good, My female favorite F/A is Shalhevet, Male is Ran...

Thanks,
Eran.
