Airlines shouldn't be allowed to shrink the seat-size any more. Period. It's not only screamingly uncomfortable for anyone with long legs or a body shape that doesn't look like a pencil, it's also unsafe. On one flight the guy who boarded last, behind me (I always board toward the end, hate fighting my way to my seat), he was Samoan & must have weighed 300lbs. It wasn't muscle, sad to say. He had a look of fear in his eyes when he realized his seat was the middle one, between me & a 9 year-old girl traveling with split family seats. There was no way he was going to fit in that small seat without spilling out both sides, crowding all three of us into the narrow space between rows. And it was a full flight. So I stood up, told the man he could switch seats with me, and being the window seat he'd have a bit more room & could lean back into the window area. You could just *feel* the relief and gratitude pour out of him. I gave him the armrest, and he was even able to nap on the way home.
