I was on F from ORD to MAD and then in C on to STR a few month ago.
The seats are similar to the old F of AA (full flat). DOnt know about food and service. I was the only one in F and sleeping till about 10 minutes before landing. Crew was nice, let me sleep and tried to be quiet.
Lounge in MAD nice, C on the flight to STR as bad as the typical inner european C.

I would fly them again any time. General impression similar to AA. But not at the top of my list.
