Just wanted to emphasize a point I made in a similar thread (regarding armrests) -- we all simply need to be cognizant of those around us!!!

As someone who is 6'1"/285, I can sympathize with tall individuals as well as wide individuals. However, as large as I am, I try my best not to intrude on others. I've had smaller people recline their seats with no regard to the fact that I'm crammed into the seat behind them. Now, I am not suggesting "kicking them in the back", even though I have been berated (literally with looks of disgust or rude comments) time after time for simply asking someone politely if they'd mind sitting upright.

At 6'1", believe me, I understand taller people wanting to recline their seats. Do they have the "air rights" above my lap? Perhaps... perhaps not...

After all, if someone uses the argument that the person in front of them is reclined, so what are you saying -- you want everyone behind you to recline their seat all the way to the rear of the aircraft? How does that effect the person in the emergency aisle or last row?! They cannot recline their seat even if they wanted to.

My point is this -- if you are taller, and notice the person behind you is also tall or large, to take notice of this. If you are smaller, again, take notice of the person behind you. Perhaps even some seat changes are the remedy...

Regardless, the simple solution is this -- Be cognizant of your fellow passengers!
