London Heathrow Airport, renowned for its global connectivity, offers a variety of flights to Asian destinations. In February 2024, several routes stand out in terms of scheduled seat capacity, as reported by Cirium, an aviation analytics company. The list focuses on South Asia, East Asia, and Southeast Asia while excluding the Middle East.
China Eastern Airlines operates flights from Heathrow to Shanghai-Pudong with 15,072 seats available in February. This route is unique among the top ten as it leads to a destination that was not part of the British Empire.
British Airways serves Mumbai with 15,232 seats over 56 flights in February. Despite being dominant at Heathrow with a significant market share, this is British Airways' only entry on the list.
