The Resilience of London Heathrow Amid Global Air Travel Fluctuation

John Grant, OAG’s chief analyst, emphasizes the enduring prominence of Asian routes, attributing it to the region’s appeal as a tourism destination:

“Asia continues to have the busiest routes in the world due to its popularity as a tourism hotspot,” said John Grant, chief analyst at OAG. “Although capacity is not back to 2019 levels, London Heathrow remains a pivotal hub for global air travel.”
