Incheon International Airport

Seoul, South Korea

Incheon has placed first for the third year in a row, thanks to staffers' exceptional pride in welcoming travelers. Visitors just passing through can book tours of a nearby temple, a nature reserve, pottery factories, the local Chinatown, or the set of a Korean television drama. A one-hour tour costs $5. The airport also boasts a billiards hall and electronic game room, while the nearby Sky72 Golf Club welcomes players day and night. The airport also runs nightly excursions to Golden Gate Casino, a foreigners-only gambling oasis two minutes away.
