Delhi Airport Jumps to 5th Spot in Asia-Pacific Aviation Rankings in 2025
In a significant milestone for India’s civil aviation sector, Indira Gandhi International Airport (IGIA), Delhi has secured the 5th position among the busiest airports in the Asia-Pacific (APAC) region for the year 2025. This remarkable rise from 9th place in 2019 highlights the rapid growth trajectory of India’s aviation ecosystem, driven by expanding domestic travel demand, capacity expansion, and airline operations.
According to recent data from OAG (Official Aviation Guide) — a global leader in aviation analytics — the ranking is based on one-way departing seat capacity rather than sheer passenger footfall. In 2025, Delhi Airport recorded an impressive 46.18 million one-way departing seats, pushing it ahead of several major international hubs like Bangkok’s Suvarnabhumi Airport, Singapore Changi Airport, and Seoul’s Incheon International Airport.
🛫 Factors Behind Delhi Airport’s Rise
Several key factors have contributed to Delhi’s rapid ascent in these rankings:
📊 Surge in Scheduled Airline Capacity
Delhi’s strong improvement in ranking is primarily due to the dramatic increase in scheduled seat capacity — a measure that reflects both domestic and international connectivity. This growth mirrors the sharp rise in demand for air travel across India after the pandemic, with domestic routes playing a significant role.
🏙️ Boost from Airline Expansion
Major domestic carriers, particularly IndiGo, have aggressively expanded their flight networks, adding new routes and increasing frequencies. The airline’s focus on affordable pricing and wider reach — especially to tier-2 and tier-3 cities — has driven higher travel demand and increased seat capacity at Delhi Airport.
🚀 Growth of India’s Aviation Market
India’s aviation sector has been one of the fastest-growing in the world in recent years. According to industry data, India has become one of the top global markets in terms of airline capacity, with consistent double-digit growth in scheduled seats and a rapidly rising consumer base.
🌍 Significance of APAC Ranking
The Asia-Pacific region represents one of the most dynamic aviation markets globally, encompassing major hubs from Japan, China, Southeast Asia, and the Middle East. Delhi’s presence among the top five busiest airports in this competitive environment signals India’s strengthening role in regional and global aviation.
