>>1236958Okay.
>WidthFixed by airplane design. You can't make seats wider.
>PitchCan be changed. Some people like more pitch, so they book seats near emergency exits.
From my experience, 5-6 cm won't make a difference. Only 20-30, like near exits, will make some noticeable difference.
>adjustable headrestI don't know about this. For me it is just one more thing to adjust, that gives no benefit.
>back supportAll seats have more-less identical. And it is not required, plane is not a drift car, you don't experience much yaw action.
>power outletsI have never seen 110/220V outlets.
Saw only couple times a USB outlets. And why would you even need an USB charger? Phone doesn't work at 35000', WiFi is expensive, and using it on phone is just painful.
Watching pre-pirated films on tablet? I don't think those outlet will give 2A.
>screensThe only thing that differs quite a lot from company to company. Exists only in long haul flights, never seen this in small planes like 737.
Some companies still have VHS (no jokes), and a lot of monitors in seats. You have no options, beside turning it on or off, or adjusting volume. Sometimes there are multiple channels available, but due to shitty maintenance, this doesn't work, and for some strange reason is still not on fire.
Some have pretty decent GNU/Linux powered devices, with many films and shit. And it is quite annoying, when you are trying to sleep, and faggot near you watches it at full brightness.
Planes are just awful, unless you work on them. I think crew has much better conditions, especially in long haul flights.
