7 hours? where are you flying from/to? What airline? hehe if its AA
go to the K gates and you can see the intl arrivals happen from about 12.00 -> 3.00 pm! If your on United, feel free to take the underground walkway a few dozen times to make sure the light show hasnt repeated and to watch the UA
Easy Update. Thats fun to watch. hehe. Terminal 2... well there's really nothing appetising to see. You can into T5
but just to the arrivals hall... i guess you could stand there and see people from all different countries come out ... Its fun to see where they are coming from/airline and to take pictures of the crew! Any other questions feel free to email me!
