First, have a HUGE row with your girlfriend, wife, partner, lover, friend with benefits. Whatevs.
Make sure the whole of the aircraft hears how much you really really hate them.
Be considerate. Take the row to a quieter place… say, for example, the toilet. Together.
Lock the door. BAM.
Make sure you scream and shout really loudly. You need to ensure the plane knows you are having the wildest of rows.
Now for the exit. You hate each other, remember.
Perfect. Mission complete. Thanks Jimmy Tatro.
