No. Should not be allowed. For some reason airlines have been allowed to narrow that space more and more to the point where it’s just not reasonable to use. You are infringing on the person behind you. Sure it’s mainly the airlines fault, and the government regulators that are supposed to serve the people, but don’t be an asshole about basic human courtesy

• for those of us on the taller side, you reclining can be painful on the knees. How is it any different than me walking by punching your shoulder. Should I do that? Not ok
• for those of us on the taller side, if you recline, we may no longer easily see the whole screen
• Even short people no longer have room for a laptop and reclining means you quite likely damage it. That’s not ok
• While the trays are supposedly independent, if reclining, they aren’t entirely. You reclining will bump the tray and potentially spill a drink. Not ok. On some aircraft the recline will partly crush a tall cup or can on the back of the tray or knock it over. Not ok
• those of us on the bigger side may no longer even fit a standard paperback. Now you’re not even letting me read because you feel entitled?

As someone both big and tall, I have had people in front of me recline so my normal breathing is in their hair. I have to admit to playing that up. My edgy revenge fantasy is to rest my novel on top of their head because it literally would be easier to read than in front of me
