Flying from Europe to the Gulf, EKs eco class on A 332s and B 777s are as good as BAs-AFs-LXs however the A 345 from LGW
is a bit better because of the high quality Inflight Entertainment avbl on video in Eco class.
As for me paying premium for EK
F & J from Europe to the Middle East, I would only do so on the A 345 operated LGW
flight and not on anyother aircraft operated flight of EK
If you want to fly business class from Europe to DXB
then the best two choices are BA
(SWISS) or GULF AIR AIRBUS A 330-200 (332) only...their A 343s are not that great at all in any class...they dont have tvs in every seat, F class pitch is only 62 inches whilst J is 50 whereas their A 332 has a seat pitch of 82 in F and 60 in J and all seats in F-J-Y have tvs.
However at the end of the day, my choice for Business class from Europe to the Gulf would be on a BA
B 777 or B 744 or LX
