I just did two 5+ hour legs in the rows 3 and 4 window in the NEO. SEA - KOA and KOA - LAX
I'll be blunt! The New first class seats suck!
While the storage features are nice, they come at the price of reduced width seats that force you into an upright posture for the entire trip. The seats themselves are enclosed in plastic shells resembling a D1 seat that include privacy "wings" at head level that obstruct views out the window and effectively trap you in your seat when the passenger in front reclines. The lack of space also makes it impossible to use a laptop when the passenger in front reclines.
Accessing the aisle from the window seat requires that the row in front of you to bring their seats fully upright. I found the seats claustrophobic, the "memory foam" is thin and became very uncomfortable after about three hours. I could have felt this "squished" in main cabin for a lot less money!
Never been so happy to see the overstuffed, wide seats on my 738 connection to ANC
Come on Delta, you can do better than this!
More Pitch and more padding!
