Looking to finalize that presentation and need to pull in a few additional pictures and stats from the Web? The Massachusetts Port Authority in January 2010 approved free Wi-Fi across Logan International Airport for two full years. That's still a rarity across the United States—especially because it's free. Beyond that anomaly, the signal strength is solid, there are plenty of power outlets throughout the airport, and seating is both comfortable and readily available. Unlike many airports that require a purchase of time or multiple login screens, this unlimited usage allows you to get all the work done you can to while waiting to board.

COST: Free.
