Newark Liberty International and three other tri-state airports frequented by New Jersey travelers have managed to win less-than-coveted positions on a new "worst airports" list.

The "Guide to Sleeping in Airports" ranks Newark fourth on its "10 Worst Airports in North America" list, trailing worst-of-all LaGuardia, among others.

Failing to be quite as miserable are John F. Kennedy International (fifth worst) and Philadelphia International (sixth worst).

As the winter months approach, air travel can become more tedious and cumbersome than usual, especially at airports where weather conditions cause flight delays and cancellations. In those circumstances, travelers can be stranded for hours or even days a at time.

According to the survey, Newark does very little to make visitors comfortable inside its sprawling complex, where the features include "unattractive construction," too much seating with armrests (translation: no place to nap) and plenty of cold floors.

"People who are delayed in the airport like to stretch out or have somewhere to relax while they're waiting," said Donna McSherry, founder of the guide. "At Newark, the temperature in the terminal is kept cold, even during the winter months, and the WiFi isn't free -- which is one of the top complaints."

So, what must an airport do to make the list of best airports?

"They just need to offer more services to passengers, McSherry said. "For example, if you look at San Francisco, there are showers and art galleries and even aquariums that keep people busy while they're waiting. Some airports will have dedicated rest zones with leather padded seating and leg rests for people to just relax and watch television. Some airports even have yoga studios.
