In charts: Indians have quit air travel like never before

India’s domestic air travel recovery has almost completely unwound. Passenger traffic stood at 126.6% of the 2019 level in May 2026. By September, it was only 102.9%, barely above the pre-pandemic benchmark. This makes the recent decline unusually severe.

The sharpest point came in July, when traffic fell to 101.1% of 2019 levels. It then improved slightly to 103.1% in August and 102.9% in September. In other words, 100 passengers who travelled in 2019 corresponded to only about 101 passengers in July 2026. The article links the decline to high fares, fuel costs, limited capacity, and earlier cancellations.

The downturn followed gains made from 2023 through the first half of 2025. Domestic traffic declined year on year in 10 of the past 15 months. Its July-to-September levels were worse than those recorded three years earlier, showing that domestic aviation has returned close to its pre-pandemic size rather than continuing its recovery.

Domestic air passenger traffic is the number of passengers travelling on flights within India. It measures the strength of India’s internal aviation market. International air traffic counts passengers travelling between India and other countries. The distinction matters because the two markets faced different disruptions in the article.

International traffic fell when the West Asia war closed airports, restricted airspace, lengthened routes, and raised prices. Domestic traffic faced a slower but more persistent squeeze from fuel-driven fare increases, constrained capacity, cancellations, and weaker spending. Airport traffic data from the Airports Authority of India was used to measure international traffic.

International traffic dropped below pre-pandemic levels in March and April, then recovered partly as the conflict eased. Domestic traffic, however, continued weakening and fell below international traffic relative to 2019 levels from June 2026. This shows that domestic passengers were especially sensitive to rising prices and reduced discretionary spending.

Higher fuel prices raise airlines’ operating costs, and airlines pass much of that pressure to passengers through higher fares. Limited capacity makes the problem worse because fewer available seats cannot easily absorb demand. Cancellations further reduce choices and can leave travellers facing costlier alternatives.

The article connects different pressures to different periods. In 2025, heavy rainfall, constrained capacity, weaker business sentiment, and IndiGo’s cancellations drove much of the decline. In 2026, the West Asia war sharply increased fuel prices, and the resulting fare increases became the main explanation for falling domestic traffic.

Consumers also faced broader inflation, so air travel became harder to justify as discretionary spending. Airfare inflation reached nearly 30% year on year by September, while overall travel costs rose much more slowly. With rail travel substantially cheaper, price-sensitive passengers had a strong reason to postpone flying or switch modes.

The article’s route comparison shows an unusually wide price gap between air travel and second AC rail. On popular one-way routes involving Delhi, Mumbai, Chennai, Kolkata, Bengaluru, and Hyderabad, the cheapest available airfare costs 45% to 186% more than a second AC railway fare.

That comparison covers the current pre-Diwali week, when travel demand is building. It does not mean every flight costs 186% more than rail. Rather, it shows how widely the premium varies by route and ticket availability. Airfares are dynamic, so prices can change as seats sell and travel dates approach.

The current gap is much larger than the usual average premium of roughly 25% to 30%. This makes rail a stronger substitute for price-sensitive travellers. It also helps explain why high fares have reduced domestic air traffic, even though some recovery is expected during the October-December festival and holiday period.

Air travel demand weakens when ticket prices rise faster than what people can comfortably afford. Flights are often discretionary, so households can delay them, cancel them, or choose another transport mode. The effect is strongest among passengers already facing inflation in other parts of their budgets.

India’s airfare inflation crossed 20% year on year in July and approached 30% by September. Overall travel costs also increased, but airfares rose four to six times faster. On major routes, flying was 45% to 186% costlier than second AC rail during the pre-Diwali week, giving travellers a clear cheaper alternative.

The result has been a broad demand slowdown. Domestic traffic declined year on year in 10 of the past 15 months and reached almost its 2019 level. Icra attributed the fall to elevated fares and weaker discretionary travel demand. Some festival-season recovery may occur, but a large jump is needed to regain lost ground.

The West Asia war affected international flying first because it directly disrupted routes and airports. Airports closed, airspace restrictions appeared, and flights to other destinations needed longer routes. These changes immediately reduced international capacity and raised prices, pushing international traffic below pre-pandemic levels in March and April.

Domestic aviation faced a different transmission mechanism. The war sharply increased fuel prices, but the effect on domestic passengers came as airlines passed those higher costs into ticket prices. That process affected affordability with a lag. Domestic demand also faced existing problems, including constrained capacity and weaker spending.

As the conflict eased, international traffic recovered to some extent. Domestic traffic did not rebound similarly because high fares and inflation created a more persistent demand problem. Since June 2026, domestic traffic has been lower than international traffic relative to 2019 levels, showing the domestic impact became more structural.

Jet-fuel prices are a major pressure on airline costs, so a sharp increase can lead airlines to pass more expense to passengers through higher fares. Capacity matters too. When fewer flights or seats are available, airlines have less inventory to sell and passengers have fewer alternatives.

Dynamic pricing then adjusts tickets according to changing availability and demand. As cheaper seats sell, the remaining seats can be offered at higher prices. The article notes that airfares are dynamic, which makes it difficult to calculate one average increase from ticket prices alone. Its route comparison captures the result: air was 45% to 186% costlier than second AC rail.

These forces reinforce each other. Fuel inflation raises the cost base, constrained capacity limits supply, and dynamic pricing widens fare differences across routes and dates. The article reports airfare inflation near 30% by September. Such prices have reduced domestic demand and brought traffic close to 2019 levels.
