We have all been there before.  Your flight has been delayed, or even cancelled, and you are stuck in a lousy airport for hours-upon-hours.  It’s a horrible experience.  On the flip side, we all have airports that we genuinely enjoy.  I wouldn’t go so far as to say that we would like to use our free time to hang around at them, but these airports go above-and-beyond to make the experience for travelers less stressful.
