I want to stop entitled recliners from eating up my leg room on flights
What is wrong with them sitting their seats back?
I'm a very tall person and it's annoying me whenever they fold their legs.
I think that you should ask them! If they are hurting your legs, you should ask them to put their seats up.
I know! But I have no hope that they will do it.
Well, you won't know until you ask them. Be polite and show them how tall you are and ask nicely. I bet they comply!
