rest areas are class 2. One aircraft has them in the first row, the other aircraft have them in the back. Most pilots don’t use the first row seats because when you lean back to rest position, you’re looking up at the passenger in the row behind.
You can preselect your crew meal from the passenger menu on a quarterly basis (you can change your request anytime). Most pilots would agree crew meals are pretty good. “Snacks” options are very basic. Only complaint is that FA’s have been instructed to feed the crew their meals last - this has caused some friction when flights are full.
