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.
How Indian airport passenger volumes have evolved
The Indian aviation market crossed 415 million annual passengers in FY26, recovering well past the pre-pandemic peak and continuing the structural growth trajectory that has made India one of the world's fastest-growing aviation markets. The top 10 busiest Indian airports together handle roughly 75 percent of national passenger traffic, with the remaining 25 percent spread across the broader network of AAI and private airports.
The ranking of the top 10 has shifted meaningfully since 2020. The pre-pandemic ordering led by Delhi and Mumbai has largely held at the top, but several airports have moved up the list driven by accelerated infrastructure investment and route expansion. Bengaluru has consolidated its position as the clear number three, Hyderabad has overtaken Kolkata in international passenger share, and Goa Mopa has joined the top 10 alongside the older Goa Dabolim. The Tier-1 metro airports are growing but at slower rates than the strong Tier-2 cohort.
This article ranks the top 10 by total annual passenger volume (domestic plus international), explains the growth dynamics at each, and highlights the operational story that drives the numbers. Understanding which airports are growing fast and which are constrained matters for travellers — it shapes where new routes launch, where infrastructure investment is happening and where the next decade of Indian aviation will be most visible.
1. Delhi (DEL) — Indira Gandhi International, the volume leader
Indira Gandhi International Airport handled over 76 million passengers in FY26, retaining its position as India's busiest airport by a comfortable margin. The three-runway configuration with the parallel 11/29 runways supports peak-hour capacity of around 80 movements per hour, and the new fourth runway 10/28 with Eastern Cross Taxiways is operational. Terminal capacity across T1, T2 and T3 is approximately 100 million passengers annually, with the proposed expansion to push past 130 million in long-range plans.
The international share at DEL is approximately 22 percent of total passenger traffic, with 60+ international destinations served by 75+ airlines. Air India operates its primary hub at DEL with the new wide-body fleet, IndiGo operates the most domestic frequencies, and major foreign carriers including Emirates, Qatar Airways, Lufthansa, British Airways and United have substantial DEL operations. The new Terminal 1 expansion lifted domestic capacity in 2024-2025, and progressive T3 international upgrades continue.
The operational challenges at DEL are winter fog season, which can disrupt 40 to 60 flight days annually with delays and diversions, plus peak-hour congestion on the airfield and at immigration. The remedial investments include CAT-IIIB low-visibility ILS on the main runways, dedicated CAT-III training programmes for crew, and expanded immigration e-Gate deployment. For frequent travellers, building 90-minute buffers at DEL during winter is sensible.
2. Mumbai (BOM) — Chhatrapati Shivaji Maharaj International
Chhatrapati Shivaji Maharaj International Airport handled approximately 60 million passengers in FY26, holding its number two position. The single-runway constraint (the main 09/27 runway with cross runway 14/32 used in limited configuration) caps peak-hour movements at around 50, which has been the airport's defining operational challenge. T1 handles domestic, T2 handles international and select domestic, with combined capacity approximately 65 million.
The Navi Mumbai International Airport (NMI), being built by Adani Group, is the structural solution. Phase 1 operations targeting 2026-2027 commencement will progressively absorb BOM traffic, particularly low-cost and Tier-2 domestic flights. NMI Phase 1 has 20 million passenger capacity scaling to 90 million in later phases. Once NMI is fully operational by 2030, the BOM-NMI combined Mumbai aviation system will support over 130 million annual passengers.
Until NMI is operational, BOM operates at capacity constraint. Slot availability for new airlines is essentially zero at peak times. Air India and IndiGo dominate slot holdings, with Vistara slots having transitioned to Air India post-merger. The international share at BOM is approximately 30 percent of total — higher than DEL because Mumbai is the natural international gateway for western India. The terminal experience post the T2 expansion is among India's best, with the Mahatma Mandir lounge product genuinely world-class.
3. Bengaluru (BLR) — Kempegowda International, the fastest grower
Kempegowda International Airport handled approximately 42 million passengers in FY26, with growth rates among the highest of the top 10. The two-runway configuration with parallel 09L/27R and 09R/27L supports peak movements of around 60, with the second runway 09L/27R commissioned in 2019 unlocking significant capacity. Terminal 2, opened in 2022 with Phase 2 expansion completing in 2024, lifted total terminal capacity past 50 million.
The international share at BLR is approximately 25 percent of total. The international network has grown substantially through 2024-2026 with new launches including BLR-PEN Penang on IndiGo, BLR-FRA fourth-weekly on Lufthansa, multiple Gulf additions on Akasa, BLR-AMS Amsterdam on wet-leased IndiGo, and progressively more US frequencies on Air India. BLR has positioned itself as India's leading tech-travel airport with strong connectivity to global tech hubs.
The Kempegowda terminal product is one of India's most distinctive, designed by Skidmore Owings and Merrill with a biophilic design philosophy and substantial use of natural materials. The lounge product, F&B selection and retail are competitive with the better Southeast Asian hubs. The ground transportation connectivity has improved with the Namma Metro Phase 2B extension to the airport progressing, with target completion in the 2026-2027 window.
4. Chennai (MAA) — the historical southern gateway
Chennai International Airport handled approximately 25 million passengers in FY26, retaining its number four position. The airport operates two main runways (07/25 and 12/30) with limited capacity for simultaneous operations. The new Phase 2 terminal opened in phases through 2024-2025, expanding capacity to roughly 35 million annually. The international block has been progressively upgraded with more immigration counters and improved baggage systems.
The international share at MAA is approximately 30 percent of total — Chennai is historically India's largest international air gateway for the southern catchment, with strong traffic to Southeast Asia, Sri Lanka and the Gulf. Singapore Airlines, Malaysia Airlines, SriLankan, Emirates, Etihad and Qatar Airways all maintain substantial MAA operations. Indian carriers including Air India, IndiGo, AI Express and SpiceJet operate deep international networks from MAA.
The operational character of MAA is distinctive — substantial transit traffic from the southern Tier-2 cities (CJB, MDU, TRZ) connecting onto international flights, plus a strong cargo operation supporting the Chennai automotive industrial cluster. The new metro Phase 2 extension to MAA is progressing, which would substantially improve city access. The airport remains the natural southern gateway despite the rise of Bengaluru and Hyderabad.
5. Hyderabad (HYD) — Rajiv Gandhi International, the international over-performer
Rajiv Gandhi International Airport at Hyderabad handled approximately 26 million passengers in FY26, putting it close to Chennai and growing faster. The single runway 09L/27R configuration supports peak movements of around 35-40, with a proposed second runway under planning. The terminal capacity has been progressively expanded with the new Phase 4 expansion completing in 2025, lifting terminal capacity past 30 million.
The international share at HYD is approximately 27 percent of total, which is high for a non-coastal Indian metro. The international growth has been driven by the Hyderabad tech industry outbound travel, US student traffic, and the substantial Telugu diaspora in the Gulf and Southeast Asia. New launches in 2024-2026 included HYD-HKG Cathay Pacific restoration, HYD-PHK on AI Express, HYD-KUL on IndiGo, plus deeper Gulf coverage. The airport has consistently been rated among India's best for passenger experience.
The GMR Group operation at HYD has invested in lounge product, retail, and ground services. The unique selling point is operational efficiency — minimum connecting time of 45 minutes for international transit is industry-leading, the baggage system is reliable, and the on-time performance environment is favourable. For Telugu-origin travellers and the tech industry, HYD has become a credible alternative to BLR for international travel.
6. Kolkata (CCU) — Netaji Subhas Chandra Bose International
Netaji Subhas Chandra Bose International Airport handled approximately 22 million passengers in FY26. The single runway configuration with cross runway support handles peak movements of about 30. The integrated terminal opened in 2013 has approximately 26 million capacity, with progressive expansion under planning to support medium-term growth.
The international share at CCU is approximately 18 percent of total — lower than other top metros because Kolkata's international network depth has lagged growth elsewhere. Major international destinations include the Gulf (DXB, AUH, DOH, RUH on multiple carriers), Bangkok and Singapore on multiple frequencies, and select European routes. The CCU airport has been working through 2024-2026 to add more international carriers and frequencies.
The competitive context for CCU is meaningful. With Bhubaneswar (BBI) growing fast and gaining direct international service, the historical pattern of eastern India travellers transiting through CCU is gradually shifting. CCU remains the dominant gateway for West Bengal and the broader east, but its growth rate is slower than BLR, HYD or BBI. The infrastructure investments through 2026-2028 will shape whether CCU recaptures international growth or whether the eastern aviation market increasingly distributes across BBI and CCU.
7-10. Cochin, Ahmedabad, Pune, Goa Mopa — the next tier
Positions 7 through 10 in the FY26 ranking are Cochin (COK), Ahmedabad (AMD), Pune (PNQ) and Goa Mopa (GOX). Each is in the 10 to 17 million passenger range and each has distinct growth dynamics.
Cochin (COK) handled approximately 15 million passengers in FY26, with international share approaching 40 percent — the highest of any top-10 Indian airport. The Kerala outbound to the Gulf, Southeast Asia and North America drives the high international share. COK is one of India's earliest privately operated airports (CIAL) and is the world's first fully solar-powered airport. The Cochin Special Economic Zone proximity supports cargo growth alongside passenger traffic.
Ahmedabad (AMD) handled approximately 14 million passengers, with the airport's transition to Adani Group management driving terminal upgrades and operational improvements. The international network has deepened with more Gulf carriers and the resumed Etihad AUH-AMD service. Pune (PNQ) handled approximately 12 million passengers — the long-promised new Pune greenfield airport at Purandar continues progressing, which would dramatically expand Pune aviation capacity.
Goa Mopa (GOX), opened in 2023 as North Goa's new greenfield international airport operated by GMR, handled approximately 11 million passengers in FY26 — extraordinary growth for a newly-opened airport. Combined with the existing Goa Dabolim (GOI), Goa's aviation system handles over 20 million passengers, making Goa one of India's most aviation-dense states relative to population. The combined GOI plus GOX international network is one of the deepest among non-metro Indian aviation markets.

Ranking shifts and the outlook for 2030
Comparing the FY26 ranking with FY20 shows meaningful shifts. Bengaluru moved firmly into number 3 ahead of Chennai, reflecting Bengaluru's structural growth. Hyderabad has narrowed the gap with Chennai significantly. Goa Mopa has entered the top 10, displacing some smaller airports. The metro top three of DEL, BOM and BLR is stable but the gaps are widening — BLR is growing fastest of the three.
Looking forward to 2030, the projected ranking shifts could include: Bengaluru potentially overtaking Mumbai if Mumbai's slot constraint continues without Navi Mumbai fully operational; Hyderabad potentially overtaking Chennai with continued tech-driven outbound growth; Bhubaneswar potentially entering the top 10 if international growth continues; and Bhogapuram emerging as a significant Tier-2 hub on the eastern Andhra coast. The DEL position at number one is structurally secure for the medium-term.
For travellers, the practical implication is that airport choice for international travel is becoming more nuanced. The traditional default to a metro is no longer always the best — secondary airports like COK, GOX, AMD and now BBI offer competitive international options with better passenger experience and often better fares. The 2030 Indian aviation map will look different from 2020, with more spread across more airports and shorter average journeys for the average Indian traveller.

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.
