However, turbelence can also be a big issue over mountains due to unpredictable updrafts, so that probably has a big role to play.
On Aerolineas Argentinas seatbelts are seemingly optional, depending on how many pressing issues the FAs have to discuss while they hide.
On one flight there was zero pre-landing check. I saw tray tables down while landing so I presume many seatbelts went unused.
Oh, they never came through and picked up the rubbish from the budgie smuggler butties they tossed at us for lunch! The cabin was a right mess!
