US airports continue to lead the world when it comes to making large airports work as Megahubs. Nine of the Top 10 Megahubs are located in the US, one more than in 2015.
Overall, there are 22 US airports among the Top 50 Megahubs.
Chicago O’Hare International Airport (ORD) is the largest mega hub in the world, according to OAG’s recently-released Megahub Index 2016.
On a single day in August, there were over 270,000 possible connections between flights arriving at ORD and flights departing within a six-hour window.
The highest ranking Megahub outside of the US is Jakarta’s Soekarno–Hatta International Airport (CGK) in Indonesia, which is ranked in 7th place. On the busiest day there were over 40,000 potential connections between flights within six hours, connecting passengers between 71 destinations.
London Heathrow Airport (LHR) is the highest-ranked Megahub in Europe, ranked 15th overall. Last year it was placed well ahead of other European rivals but the gap appears to be closing with Frankfurt (FRA) ranked 20th and Amsterdam (AMS) ranked 21st.
Sao Paulo Congonhas Airport (CGH) is the largest Megahub in Latin America but its ranking has fallen since the 2015 edition, from 7th place to 23rd.
Top 25 Low-Cost Megahubs
While traditionally connections have been made between IATA airlines, increasingly passengers are self-connecting between low-cost carriers.
Airports and the airlines themselves are beginning to facilitate connections between low-cost flights.
OAG has therefore included in this year’s Megahubs Index the Top 25 airports for online connections (i.e. connections between the same carrier) for low-cost airlines.
US airports top the rankings for Low-Cost Megahubs, holding the top five places. The top three are each airports that are dominated by Southwest Airlines, the original low-cost carrier. Phoenix Sky Harbor International Airport (PHX) in 4th, is dominated by American Airlines and Denver International Airport (DEN) in 5th, is dominated by United Airlines; however Southwest is the no.2 carrier at each airport by some distance.
Chicago Midway Airport (MDW) is ranked number 1 for the second year in a row, with Southwest operating nearly 90% of the flights in August 2016.
Outside the US, Gol has created the best Low-Cost Megahub at Sao Paulo Congonhas Airport (CGH).
In Thailand, Don Mueang Airport (DMK) in Bangkok is the highest-ranked Low-Cost Megahub outside the Americas, with carriers within the AirAsia group representing almost half of the scheduled flights in August.
Istanbul’s Sabiha Gokcen Airport (SAW) is the largest European Low-Cost Megahub. New to the Top 25 Low-Cost Megahubs this year are Bengaluru International Airport (BLR) in India and Fort Lauderdale Airport (FLL) in the US, where IndiGo and JetBlue lead the way, respectively
