Most Connected Airport in the World in 2023

OAG released today its Megahubs 2023 rankings of the most internationally connected airports in the world. The 2023 Megahubs Index analyzes the efficacy and connectivity of the world’s international hubs.

London Heathrow Airport (LHR) is the most connected airport in the world this year in first place. LHR is the 4th biggest airport in the world in terms of total scheduled capacity in the year to August 2023. British Airways remains the dominant airline at London Heathrow, operating 50% of all flights.

London Heathrow Airport also ranked first in 2019, and while the number of potential connections in the period selected still remains slightly below 2019 levels, London Heathrow ranks highest this year in terms of the ratio of those connections to destinations served.

New York’s JFK Airport (JFK) is 2nd in this year’s Megahubs Index. New York (JFK) punches above its weight with high volumes of potential connecting options across its extensive network, and sits just outside the Top 10 largest global airports by scheduled seat capacity.

JFK has moved up the rankings considerably from 18th position in 2019, in part driven by American Airlines operating seven more international destinations in 2023, and new services from several carriers including Qantas, Air New Zealand and Air Senegal.

Other Megahubs of significance include Atlanta (ATL) which ranks 14th and Chicago O’Hare (ORD) which sits in position 10, down from 3rd place in 2019.
