Those who fly to or from New York are fully accustomed to long security lines, labyrinthine paths to the terminal, flight delays, cancellations and other unpleasant happenings, not to mention the arduous or expensive journey to the airport itself.

According to a study by The Points Guy, a travel publication, those customers have the right to complain. The three New York-area airports are the three worst among the nation’s 30 busiest airports, based on a study that considered timeliness, accessibility and amenities.

La Guardia Airport, famously described by Vice President Joseph R. Biden Jr. in 2014 as akin to what one would find “in a third world country,” ranked as the worst. Right behind it were John F. Kennedy International and Newark Liberty International.

“People don’t realize what we have is a lot worse than what other people deal with,” said Brian Kelly, a New Yorker and the founder and chief executive of The Points Guy.
