actually not true. not every seat has a recline function. the seats in front of an emergency exit do not have a.recline function , nor do the seats between a double overwing exit. however the best seat in the house in coach is the row thats at the aft overwing emergency exit. this row does recline because theres no exit behind it. the row at the fwd overwing exit has extra room but these do not not recline as it will interfere with emergency egress from the aircraft aft overwing emergency exit thats behind it
typically your seat spacing is 31" from front track locking pin, to front track locking pin seat to seat. emergency exit rows are typically 36" from locking pin to locking pin. so your aft overwing emergency exit row which i try to get everytime i fly has extra legroom, and reclines. works great since i have bad knees.
how do i know this, well i am an airline heavy maintenance mechanic.
