The World's Most Amazing Airport Lounges
Where it is: Heathrow Airport, Terminal 5
What it's like: Opening in March 2008, this lounge for first-class flyers includes a bar with floor-to-ceiling glass walls overlooking the airport (the better to gloat over less-fortunate travelers), and a restaurant with intimate booths offering all-day dining. Three private cabana rooms with beds and ensuite bathrooms can be reserved in advance; a wide range of spa services will also be available at the adjacent Elemis travel spa. Staff at the lounge's dedicated concierge desk will do everything from booking theater tickets and calling taxis to changing flight reservations (in case you want to stay a little longer).
