PSA for anyone using a laptop during flights, the tray tables do not change angle or height when the person in front of you puts their seat all the way back. I almost had someone break my laptop screen a few years ago because the top of my screen got caught under the exposed edges where my tray table would fold up into, as rhe seat back came angling down towards my tray table. I was quick enough to be able to pull my laptop towards me and remove the screen before the full force was applied to the screen housing.
