Simply put, flying can be a stressful activity.
A lot of the time it begins with the airports: dizzying parking garages, overpriced food and a series of long lines have a way of making even the most serene travelers a little bit agitated. And that’s even before the airplane leaves the ground. So it’s easy to see how poor service from an airline can put the finishing touches on a ruined day — long check-in lines, flight delays, lost luggage, baggage fees and general rudeness have a way of doing that. Not to mention the scary food (at least it used to be free scary food).
