I once fly from Anchorage to Denver in a seat like that at the rear bulkhead that did not recline. It was hell. I would never do it again. The seats like that should be forbidden.
The back seats don’t recline. If you want reclining seats, don’t take the back seats. If that is all that is left, take another flight.
I see not reason to remove 5-6 seats from the available pool of seats, just because some people don’t like them.
They should be listed as non-reclining on the web site, so people who rarely travel would know this.
I often sit in the back row, because nobody wants to, so you are more likely to have a free seat next to you, plus you are close to the peanuts, or whatever it is they feed you these days.
