Heathrow has one of the world’s largest catalogues of airlines with over 80 different carriers from many different countries using its runways and terminals . The major airlines such as British Airways, Virgin Atlantic and Emirates have multiple flights a day whereas others pop in maybe once a week. Some of the legacy airlines such as Qantas and Are Lingus have been with Heathrow since the early days but others, including the new crop from China, are more recent arrivals.
