The U.S. East Coast is expecting another winter storm this weekend -- for some cities like Boston, it's the fourth in as many weeks. Winter storms bring flight cancellations and delays, and not necessarily in the cities where the storm hits, either. The ripple effect can mean passengers in cities with milder climates might get stuck, too.

While no one wants to spend their free time in an airport, eating expensive, tasteless food or trying to relax in an uncomfortable airport seat, there are some airports that make the experience a bit more bearable. Dating destination site MissTravel.com polled more than 50,000 people on the comfort, convenience, customer service and cleanliness of airports across the U.S. Here's what they found:

PDX: Portland International Airport

Portland's hipster reputation, lampooned in the sketch comedy show "Portlandia," extends to its airport, as well. Travelers can eat from food carts featuring award-winning Asian cuisine and shop at stores like Made in Oregon and The Real Mother Goose, which showcases handmade products. Wi-Fi is free for all, of course.

SAV: Savannah/Hilton Head International Airport

You can go back in time at this small airport in Georgia, which features a historic Southern street with benches, a mock square and a giant clock that hangs from the ceiling.

SFO: San Francisco International Airport

The opposite of the laid-back atmosphere at SAV, San Francisco's airport reflects the city's tech-savvy, modern vibe. Wi-Fi is free, and there are dozens of trendy shops and restaurants to browse. You can while away the delayed-flight hours browsing ever-changing exhibitions like "When Art Rocked: San Francisco Music Posters" and "Joseff of Hollywood: Jeweler to the Stars." There's even a place called "Freshen Up!" where you can grab a quick shower for $15.

PBI: Palm Beach Inernational Airport

This compact airport is easy to navigate, and tired travelers can check out Comfort Zone, a full-service day spa. If you're into golf, this airport's for you: There's a putting green just beyond the security area. Need help with something? PBI's "Airport Ambassadors," dressed in teal jackets, are ready to assist passengers with any information needs.

PHL: Philadelphia International Airport

Philly's airport has a "Just Plane Fun" fitness area outfitted wih elliptical machines and stationary bikes so you can get a workout between flights or when you're stuck. Bored? Check out "Art at the Airport," featuring rotating exhibitions located throughout the airport.
