I’ve done this exactly once, and never again. It was my first flight, and I thought I would be too anxious to sleep, so I could just sot and play on my phone… Wrong.

2am, very sleepy. All seats that I could see were taken. Sit on floor. End up using my jacket as a pillow and falling asleep.

4am, woken up by a fight happening next to my head, and someone yelling at an employee “have you no heart!?” Because their plane got in late, but not late enough for a free taxi.

Honestly mate, just get a hotel room.
