Digital flight information company, OAG, has released Megahubs International Index for 2018.

The report reveals the 50 most internationally connected airports in the world. The index is generated by comparing the number of scheduled connections to and from international flights with the number of destinations served from the airport.

OAG has calculated the total number of all possible connections between inbound and outbound flights within a six-hour window, where either the inbound, outbound, or both flights are international, at the largest 200 airports in the world (based on total scheduled seats in July 2018) and at the largest 200 international airports (based on total international scheduled seats in July 2018) on the busiest day for global aviation over the 12 months to July 2018.

The most internationally connected airport in the world is London Heathrow Airport (LHR). With an International Connectivity Index which is higher than its nearest rival by some margin, LHR ranks as the world’s No. 1 Megahub. On the busiest day for aviation in 2018, there were 66,000 possible international connections between flights arriving and departing at the airport within a six-hour window. Dominant carrier was British Airways with a 52% share of flight at hub.

Chicago O’Hare (ORD) has moved up the Megahubs index and is ranked in 2nd place this year. The airport has more potential international connections on the busiest day but these are spread across a greater number of destinations. Dominant carrier was United Airlines with 48% share of flights.

The largest Megahubs in Asia Pacific are all located in South East Asia. Singapore Changi Airport (SIN) ranks 8th overall, followed by Jakarta Airport (CGK) in 10th place. Kuala Lumpur Airport (KUL), Hong Kong Airport (HKG) and Bangkok Airport (BKK) are also within the top 15 International Megahubs.  Incheon (ICN), makes it into the top 15 International Megahubs in 15th place.

Istanbul Airport (IST) comes in just ahead of Dubai International Airport (DXB) in 17th place with 55,000 possible international connections within a six-hour window.

The top place for the low-cost International Megahubs remain as they were in 2017, with Kuala Lumpur Airport (KUL) ranked in 1st place. Low-cost carrier AirAsia dominates the airport with 40 percent of flight operations.
