Delhi Airport Beats Dubai in Global Connectivity: What Indian Travellers Should Know

Delhi's Indira Gandhi International Airport has moved ahead of Dubai International Airport in the latest global airport connectivity rankings, marking a significant change in the international aviation landscape.

According to the OAG Megahubs 2026 report, Delhi Airport climbed 11 places to rank 28th among the world's most connected international megahubs, up from 39th in 2025. Dubai, meanwhile, fell from 15th to 31st.

The ranking highlights Delhi's growing role as a connecting hub for international travellers, particularly as Indian airlines expand their networks.

Delhi Airport Ranks 28th Globally

Delhi Airport recorded a major improvement in the 2026 OAG Megahubs ranking.

The airport moved from 39th position in 2025 to 28th in 2026, making it the only Indian airport to appear in the global top 50 international megahubs.

Delhi also ranked ninth in the Asia-Pacific region and entered the world's top 10 low-cost megahubs, ranking ninth in that category.

The OAG ranking measures the number of potential international flight connections available within a defined time window, rather than simply counting the total number of destinations served.

Delhi Moves Ahead of Dubai

One of the biggest changes in the latest ranking is Delhi moving ahead of Dubai.

Dubai International Airport dropped from 15th place in 2025 to 31st in 2026. Reports attribute part of the decline to disruptions and reduced flight activity associated with the situation in West Asia.

This does not mean Delhi has more international destinations than Dubai in every sense. Rather, Delhi scored higher under OAG's specific megahub connectivity methodology.

That distinction is important for travellers because the ranking measures the potential for connecting flights within a particular period.

IndiGo Plays a Major Role

A major factor behind Delhi's improved connectivity is the growing presence of IndiGo.

According to the latest OAG data, IndiGo accounted for around 40% of flights at Delhi Airport. The airline also accounted for about 57% of the airport's low-cost-carrier capacity.

The airline's expanding domestic network provides a large passenger base that can connect with international services from Delhi.

For example, passengers travelling from cities across India can use Delhi as a connecting point for international destinations rather than travelling to a different country to catch a connecting flight.

Delhi Has More International Connections

OAG's data recorded 2,174 possible international connections at Delhi during the ranking period, compared with 1,819 for Mumbai.

Delhi currently connects with more than 67 international destinations, according to reporting based on airport data.

This growing network is helping the airport strengthen its position as an international transfer point.

New Hub-and-Spoke Services Add to Connectivity

Another development supporting Delhi's growing role as an international hub is the introduction of a hub-and-spoke international service model.

The Ministry of Civil Aviation launched the service from Delhi Airport on June 25, 2026. The model includes features such as single check-in, through baggage handling and faster transit for eligible connecting passengers.

For travellers, these services can make international connections through Delhi more convenient when the relevant airlines and itineraries support the arrangements.

Delhi Airport's Third Runway Reopens

Delhi's connectivity growth also comes alongside infrastructure improvements at the airport.

The airport's third runway, Runway 11R/29L, reopened on September 20, 2026, following a major rehabilitation programme.

The work included runway resurfacing, improvements to airfield lighting and the addition of a new rapid-exit taxiway. The upgrades are intended to improve aircraft movement, operational efficiency and resilience.

The runway's reopening comes at a time when Delhi is handling a growing number of domestic and international services.

What Does This Mean for Indian Travellers?

For passengers, Delhi's stronger connectivity could create more options when planning international journeys.

Travellers from cities without a direct international service may be able to connect through Delhi and continue to destinations in Europe, Asia, the Middle East and other international markets.

The growing number of domestic connections is particularly relevant for passengers travelling from cities such as Bengaluru, Hyderabad, Kolkata, Chennai and other Indian airports.

More Choices for Connecting Flights

A larger international hub can give travellers more combinations of flights.

For example, a passenger travelling from an Indian regional city to Europe may be able to:

Regional Indian city → Delhi → European destination

Instead of travelling through another international hub, some passengers may find a suitable itinerary through Delhi.

However, the availability and price of these connections will depend on the airlines, travel dates and individual routes.

Mumbai Also Remains an Important International Gateway

Delhi's rise does not mean Mumbai has become less important.

Mumbai remains one of India's major international gateways and also performed strongly in OAG's low-cost megahub rankings, placing 11th globally in 2026. IndiGo accounted for around 43% of flights at Mumbai Airport and about 60% of its low-cost-carrier capacity, according to OAG data reported by the Economic Times.

Together, Delhi and Mumbai remain key hubs for India's international air connectivity.

What About Other Global Airports?

Delhi's 28th-place ranking puts it among a group of major international aviation hubs.

Istanbul ranked first globally in OAG's 2026 Megahubs ranking, with connections to more than 337 destinations. Kuala Lumpur was also among the leading Asian hubs, ranking fourth globally with connections to more than 154 destinations.

Therefore, Delhi's ranking represents an improvement in its position rather than making it the world's most connected airport.

Could Delhi Become a Bigger International Transit Hub?

The latest figures indicate that Delhi's role as a transfer point is growing.

According to airport data cited by Business Standard, international transfer passengers accounted for about 29% of Delhi Airport's international traffic, compared with 22% two years earlier.

The combination of domestic connectivity, international routes, airline expansion and airport infrastructure could support further growth in Delhi's role as an international connecting airport.

Tips for Travellers Connecting Through Delhi

If you are planning an international journey through Delhi, keep these points in mind:

• Check whether your domestic and international flights are on the same booking.

• Confirm baggage-transfer arrangements before travelling.

• Allow sufficient time between connecting flights.

• Check the terminal for both flights.

• Verify transit and immigration requirements for your itinerary.

• Check for schedule changes before leaving for the airport.

• Compare direct flights with connecting options before booking.

A connection through Delhi may not always be the cheapest or fastest option, so travellers should compare the complete itinerary.

Final Takeaway

Delhi Airport's rise to 28th place in the OAG Megahubs 2026 ranking highlights the growing international connectivity of India's capital. The airport climbed 11 places from its 2025 position and moved ahead of Dubai in this specific connectivity ranking.

The increase is being supported by IndiGo's large network, expanding international services, improved transfer facilities and recent airport infrastructure upgrades.

For Indian travellers, the development could mean more international connection options through Delhi, particularly for passengers travelling from other Indian cities.

However, the OAG ranking measures potential flight connectivity rather than overall airport quality or the total number of destinations. Travellers should therefore continue comparing individual routes, fares and connection times when planning their journeys.
