Here’s my impression.
I expected the Delta PS seat to be significantly superior than AF PE seat on 777, but honestly I didn’t feel the difference that significant. Newer, it reclines, but I didn’t sleep better.
Foodwise, Delta PS is relatively superior, but I didn’t try the new service from AF. The second meal on a transatlantic route is exactly the same as D1 (maybe just another additional choice for D1?), even on the very same tray 😂
Wine-wise, DL PS is as bad as economy. AF is way superior 😅
