What about people who fart on planes?
Or those that recline their seat all the way back as soon as the plane takes off?
Or larger people who need more seat space than others?
Or people who take a massive suitcase on as carry-on luggage as well as a handbag, coat, carrier bags full of duty-free, etc etc?
People who miss their boarding call and delay the plane?
People up and down to use the loo all the time?
Flying is tricky, we’re all sharing a confined space for a protracted period of time, plenty to get narked about if you let it.
Chill out and be tolerant
