"Undo your seatbelts and get out! Undo your seatbelts and get out!" Seems reasonable to me.
Just a question from a bloke that works on the ground.....
Why is there a need to tell PAX to undo their seatbelts?
Can anybody actually leave an a/c with a seatbelt still fastened? I mean sure they could try but they may get the row of seats that is belted to their ar*ses stuck in the door.
