I just flew the new cabin in J for the first time, thought I would share some photos with you.

The service was pretty good, and one FA was truly great. But in general, they are far from "the best" as some Lebanese would insist!

It's funny how the whole crew heavily polices the cabin for anyone using a cellphone while still on the ground and when the aircraft door is still open. I have to admit though, I experienced the same on Turkish... so they're not the only one.
Also, the seats could use some cleaning. Filth is all around the edges of the seats and is a bit surprising given how new these planes are. They also look a bit worn already!
Anyway, enjoyed both rides.
