But OP was commenting on the quality of the F class cabin based upon a photo - referring to the hard product of the aircraft.

We can talk to the cows come home as to whether the soft product on a given airline is "first" class or "economy" class or "economy plus". Thats a subject discussion that nobody is going to resolve definitively.

With respect to the hard product, I will say that AA's and US's hard product represents what every other major domestic American airline offers. 37-38 inch seat pitch in domestic first class.

If you go back 20 years, the seat pitch was similar - perhaps an inch more. COs 757-200s in 1994 had the same pitch that AAs 757s have today - 38 inches.

Airlines like LH and AF don't even offer a first class. They give you a "first" class seat with coach class seat but block off the middle seat.

You're saying thats preferrable to a domestic (i.e., United States) hard product?
