I am fed up with people on flights putting their seats back.
There is no consideration for others by these people.
Once the seats are back you struggle to get out of your seat to use the lavatory and it is so annoying when they leave their seat back throughout the meal as well.
Some even put their seats back then sit upright to watch TV. This has spoiled many a long-haul flight for us. There should be more intervention by cabin crew to make the flight comfortable for all.
