In case the gnome keeps enabling airplane more for you, here is a "work for me" solution: https://askubuntu.com/questions/965595/why-does-airplane-mode-keep-toggling-on-my-hp-laptop-in-ubuntu-18-04

I don't know what it is but everytime I closed the lid, nothing happened, I have already disabled the suspend feature in gnome tweaks. But everytime I open the lid, it enables the airplan mode, cutting the wifi.
