Into regions is better, it´s hard to pick just one! Of course my #1 choice is Virgin Atlantic, baby!
North America: American Airlines and United Airlines
South America: Varig and TAM (really impressive, check it out: www.tam.com.br)
Europe: British Airways, Air France, Virgin Atlantic and Swissair
Asia: Cathay Pacific, ANA, Qantas, Thai and JAL
Ilyushin96M: where on Air France website is the 777 tour?
