You'd think it would be one of the greatest humiliations any major airport would never allow itself to live down -- getting routinely abandoned by fed-up folks opting to fly out of Newark (Newark!) instead, where at least the ground staff cop less attitude and fewer people outside are pretending to be cab drivers.
But, nah, JFK really couldn't really care less.
Every year, more than 21 million passengers stumble through worn, mid-century terminals that peaked when The Beatles arrived in the United States and rooftop parking was all the rage; JFK proudly remains the world's busiest international air gateway.
So if you're not into a dim, surly, unbearably congested airport reeking with attitude and unapologetically long immigration lines -- good riddance.
"JFK had a piece of my luggage sitting in a little detention room for bags -- for over a year," notes one passenger. "No one noticed it was there, until finally an observant Air France employee wondered what the dusty little green bag in the corner was."
