Singapore shines as Asia’s Megahub

SINGAPORE, 27 September 2017: Based on connections and destinations served, Singapore’s Changi gains the megahub title in Asia, according to the latest OAG Megahubs International Index 2017.

If you are looking for an airport that offers the maximum connections and destinations, then of all the 16 airports in Asia that figured in the OAG top-50 annual index, Singapore led the way.

Singapore was the top ranked Asian airport and in the global-50 list it was placed 6th with a connectivity index of 257.

In the global rankings, London Heathrow (LHR) was the single most connected international megahub in the world by a clear margin. On a single day in July, there were over 72,000 possible international connections between flights arriving at LHR and flights departing within a six-hour window.

Frankfurt Airport (FRA) and Amsterdam Airport (AMS) were ranked second and third, ensuring that the top three places went to European hub airports.

The OAG Megahubs International Index 2017 monitors 50 internationally connected airports ranking them by comparing the number of scheduled connections to and from international flights with the number of destinations served from the airport.

There were some surprises in Asia.  Despite claims that Bangkok is the major aviation hub in the region, the rankings showed it trailed behind three other airports when connections and destinations were considered. Singapore ranked first in Asia, Jakarta second and Kuala Lumpur third.

Bangkok was the fifth highest in Asia, with a connectivity index of 226, while globally it stood at 13th, trailing Hong Kong that came in at fourth regionally  ( 12th on the global list) with a connectivity index of 233.

Top in Asia, Singapore (SIN) scored 35,000 possible international connections on a single day in July, giving it a connectivity index of 257,  closely followed by Jakarta (CGK), which had a connectivity index of 256. Third-placed Kuala Lumpur (9th globally ) scored a connectivity index of 243.

Kuala Lumpur’s overall high connectivity score was partly due to its strong role as a low-cost airline hub. This is reflected in OAG’s top 25 megahubs for low-cost connections.

It places Kuala Lumpur Airport (KUL), home of AirAsia, as the global no 1 followed by Jakarta Airport (CGK) in second place and Singapore Airport (SIN) third, ahead of Delhi Airport (DEL) in fourth place.

OAG says it illustrates the success of LCCs in South Asia and Southeast Asia.

Bangkok’s Don Mueang Airport (DMK) did not figure in the global-50 index.  If the connectivity index of both BKK and DMK had been merged then jointly they would have enjoyed a higher overall score. However, the OAG’s index is based on single airport connectivity.

Bangkok’s DMK did figure on the low-cost connections list that featured 25 airports. It was 8th with a connectivity index of 66, compared with first placed KUL that had a connectivity index of 134.

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 an international service. The analysis uses the busiest day for global aviation, for

the 12 months leading to July, at the world’s largest airports (based on total international seat capacity for the 12 months to July 2017).

For the purposes of this analysis, in addition to the in-built business rules within OAG’s Connections Analyser, the following customisable criteria were chosen for all operating flights:

  • Single international connections only to/from the chosen airports
  • International connections including domestic to international, international to domestic

and international to international connections

  • Maximum Connection Window of six hours
