I just completed my first round trip EWR-HAM-EWR in BF in this thing.
Never again. Besides having to leave and arrive EWR with its friendly people,
I didn't like:
1. The advertised 6'4" BF seat is way shorter than that (and we had the first row big cubby hole). I am 6'6" and couldn't sleep at all, but my 5'10" GF could not stretch out in these seats either. They are more like 5'8" useable surface.
2. The air quality is way worse than wide body, even the 767 is better
3. The staff was very lazy both ways. Hiding away and being noisy in the galley. Outbound the seatbelt sign was on the entire 7 hours
