The Year-on-Year (YoY) comparison of the number of scheduled domestic passengers carried reflects the annual growth or decline in air passenger traffic within India’s domestic aviation sector. This metric illustrates how passenger demand fluctuates over time due to a variety of factors, including economic expansion, disposable income, ticket prices, fuel prices, infrastructure development, and traveler sentiment. An increase in the number of passengers year over year is a sign of increased consumer confidence in domestic travel, better airline connectivity, and growing air travel adoption. On the other hand, a drop could be an indication of difficulties like operational hiccups, economic slowdowns, or transient shocks like pandemics or natural disasters. For evaluating the effectiveness, resiliency, and growth trajectory of India’s aviation sector, this indicator is a crucial barometer. This metric is used by investors, airline operators, and policymakers to assess capacity planning, market recovery trends, and the general well-being of the travel and tourism industry. Additionally, under government initiatives like UDAN (Ude Desh ka Aam Nagrik), the data supports airport infrastructure planning, optimises route allocations, and forecasts future passenger volumes. A robust year-over-year growth rate is consistent with India’s overall economic momentum and reflects the aspirations and mobility of the growing middle class, making India one of the world’s fastest-growing aviation markets.
