India's aviation sector has experienced substantial growth, positioning it as the world's fifth-largest aviation market. In 2024, the country handled 241 million passengers, marking an 11.1% increase compared to the previous year when it managed 211 million flyers. This growth has enabled India to surpass Japan, which recorded 205 million passengers despite a faster growth rate of 18.6%.
The United States remains the largest aviation market globally, with 876 million passengers in 2024, demonstrating a 5.2% year-on-year growth. China follows with 741 million passengers, a significant 18.7% increase from 2023. The United Kingdom ranks third with 261 million passengers, and Spain is fourth, matching India with 241 million passengers. These figures include both domestic and international passengers.
Domestic air passenger traffic within India also saw a 6.12% increase in 2024, reaching 161.3 million passengers, according to the Directorate General of Civil Aviation (DGCA).

Several factors contribute to India's burgeoning aviation market. A robust economy and a rapidly expanding middle class are driving the demand for regional air travel. Low-cost carriers (LCCs) stimulate demand by connecting emerging regions with affordable fares, holding nearly 90% of all domestic seats. The UDAN regional scheme and rising middle-class travel demand further underpin this growth.

To meet rising passenger and cargo demand, South Asian carriers are projected to quadruple their fleet size over the next two decades.

The commercial aviation segment led the market in 2024, accounting for 62.2% due to increasing demand for air travel, spurred by an expanding middle class, rising disposable incomes, and growing consumer preference for air travel.
