Indian airports handled over 415 million passengers in FY26. Here is the structured ranking of the top 10 busiest Indian airports by annual passenger volume, with growth rates and the meaningful ranking shifts since 2020.
What this article covers
How Indian airport passenger volumes have evolved
1. Delhi (DEL) — Indira Gandhi International, the volume leader
2. Mumbai (BOM) — Chhatrapati Shivaji Maharaj International
3. Bengaluru (BLR) — Kempegowda International, the fastest grower
4. Chennai (MAA) — the historical southern gateway
5. Hyderabad (HYD) — Rajiv Gandhi International, the international over-performer
6. Kolkata (CCU) — Netaji Subhas Chandra Bose International
7-10. Cochin, Ahmedabad, Pune, Goa Mopa — the next tier
Ranking shifts and the outlook for 2030
Frequently asked questions
Why does Delhi airport (DEL) handle so much more traffic than Mumbai (BOM)?
Two main reasons. First, Delhi has three runways with the new fourth runway operational, supporting much higher peak-hour movements than Mumbai's single main runway. Second, Delhi has consistently expanded terminal capacity through T1 and T3 phases, while Mumbai is capacity-constrained at T1 and T2 until Navi Mumbai opens. The Delhi airport ecosystem also benefits from being the political and corporate capital with consistent business travel demand. Mumbai is closing the gap once Navi Mumbai is fully operational.
Will Navi Mumbai (NMI) actually relieve Mumbai's capacity constraint?
Yes, materially. NMI Phase 1 with 20 million passenger capacity targeting 2026-2027 commercial start would absorb a significant share of BOM's domestic LCC operations. Full NMI capacity at 90 million in later phases would essentially create a two-airport Mumbai system handling over 130 million combined passengers. The transition is likely to be gradual, with airlines progressively shifting operations as NMI scales up. The full benefits to the Mumbai aviation system will be visible by 2028-2030.
Why is Hyderabad growing faster than Chennai in international traffic?
Hyderabad benefits from the tech industry outbound travel (Microsoft, Google, Amazon all have substantial Hyderabad operations), strong Telugu diaspora links to the US and Southeast Asia, and a higher growth rate in the catchment population overall. Chennai has historically been the southern international gateway, but the relative growth advantage has shifted to Hyderabad through the 2020s. Both airports are growing — Hyderabad is growing faster from a smaller base, narrowing the gap rapidly.
What is the typical minimum connection time at the top Indian airports?
Hyderabad (HYD) has the best published international transit MCT at 45 minutes. Bengaluru (BLR) is around 60 minutes for international transit. Delhi (DEL) and Mumbai (BOM) are 60 to 75 minutes published. Chennai (MAA) is around 60 minutes. Cochin (COK) is around 50 minutes. In practice, building 90 minute to 2 hour buffers gives comfort for irregular operations and luggage transfer. The published minimums are tight and assume on-time arrival of the inbound flight.
Is Goa Mopa (GOX) a separate airport from Goa Dabolim (GOI)?
Yes, they are two distinct airports serving Goa. GOI (Dabolim) is the older airport in South Goa, operated as a civil enclave at INS Hansa naval base. GOX (Mopa) is the newer greenfield airport in North Goa, opened in 2023 by GMR Group. The two airports are about 70 km apart. Both operate domestic and international service, with airlines progressively choosing which to operate from based on slot availability and commercial strategy. Travellers should check carefully which airport their flight uses.
Why is Cochin's international passenger share so much higher than other metros?
The Kerala outbound migration pattern is the structural reason. Kerala has a long history of professional and labour migration to the Gulf, Southeast Asia, North America and the UK. The Cochin catchment generates extremely high per-capita international travel volumes, supported by deep Gulf and Southeast Asia networks. The international share at COK approaches 40 percent of total passenger traffic, versus 22 to 30 percent at most other top-10 Indian airports. The Kerala state pattern is reflected at Trivandrum and Calicut as well.
Will Bhubaneswar (BBI) make it into the top 10 by 2030?
Plausibly yes. BBI is growing rapidly with strong domestic frequency depth and accelerating international growth. The current FY26 traffic is approximately 8 million annual passengers, which would need to grow to around 11 million to enter the top 10 displacing one of the current bottom-end entries. The trajectory supports that, particularly if international launches continue at the current pace and the Odisha state aviation market keeps growing. The 2028-2030 window is realistic for BBI top-10 entry.
How does the Indian airport infrastructure investment compare to other large Asian markets?
India's airport infrastructure investment through the 2020s is substantial — the AAI capital expenditure programme combined with private sector investment at Delhi, Mumbai, Bengaluru, Hyderabad, Goa Mopa, Bhogapuram and the Adani-managed airports represents one of the world's largest concurrent aviation infrastructure pushes. The scale is comparable to China's airport expansion of the 2010s. The pace and quality of newer terminal investments (BLR T2, DEL T1, AMD redevelopment) is competitive with the better Southeast Asian benchmarks.
