Delta should just go to a reasonable pitch instead of making passengers fight each other for comfort. It is a clear sign that they have gone way to far when they have to reduce the recline in F by 1 or 2 inches.
This attitude that the $ is more important than the customer is exactly why I left DL after 2MM miles and put over 1MM miles on a different US airline.
Unfortunately the other US airlines are following DL’s lead and becoming as crappy as the big EU airlines.
