Unless you seriously love the smell of Auntie Anne's lingering in your hair or paying $34 for a neck pillow that won't inflate properly, it's probably best to avoid Newark Liberty Airport, which is the airport you are most likely to get delayed at. Hope you brought a book!

According to the Wall Street Journal's "Middle Seat" column, 40% of the flights on the list of the top 100 chronically delayed flights either take off or land at Newark. The biggest offenders are two Delta Air Lines flights from Atlanta to Newark, one at 5 p.m. and the other at 6:45 p.m.

And don't expect to sidestep the issue by flying to Laguardia or JFK—they're not far behind in the delay department. The takeaway? Pack some snacks—you might be there be there for a while.
