LHR Terminal 3 Departures (Everything You Don't Need to Know About Code-Sharing)
London Heathrow Airport Terminal 3 2007-09-22 departures schedules.
Many of the flights are listed under the code-sharing flight numbers.
All the flights to Canada (Toronto, Calgary, Ottawa, Vancouver, Montreal) are operated by Air Canada but are listed under Scandinavian Airlines System's SK flight numbers at this very moment.
The Air New Zealand flight NZ001 is particularly interesting. From London Heathrow to Los Angeles to Auckland, it's one of the very few routes in the world that flies over both the Atlantic and Pacific oceans!
