A key feature of UDAN is the fare cap. To ensure that air travel remains affordable, the scheme sets a maximum fare that airlines can charge on UDAN routes. This fare cap is typically linked to the distance of the flight, with lower fares for shorter routes. This helps to make air travel accessible to a wider range of people, including those who may not have been able to afford it otherwise.

The Viability Gap Funding (VGF) is a critical component of UDAN. It's the financial support provided by the government to airlines to bridge the gap between the cost of operating a flight and the revenue earned from ticket sales. This funding helps to make UDAN routes financially viable for airlines, encouraging them to participate in the scheme. The VGF is typically provided for a limited period, after which the airline is expected to operate the route on a self-sustaining basis.

UDAN promotes code-sharing agreements between airlines. This allows passengers to book connecting flights on different airlines through a single reservation, making it easier to travel to and from smaller cities and towns. For example, a passenger might book a flight from Delhi to a smaller town with a connection in a larger city, with both flights operated by different airlines but booked through a single code-sharing agreement.

The scheme prioritizes the use of smaller aircraft, such as turboprops, on UDAN routes. These aircraft are more suitable for operating on shorter runways and in smaller airports. They are also more fuel-efficient, which helps to reduce operational costs. This focus on smaller aircraft allows UDAN to connect even the most remote and underserved regions of the country.

UDAN includes provisions for promoting tourism in the regions connected by the scheme. By improving air connectivity, the scheme aims to attract more tourists to these regions, boosting local economies and creating jobs. For example, a region with historical sites or natural attractions might see a surge in tourism after being connected by a UDAN flight.

The scheme incorporates a monitoring mechanism to track its progress and effectiveness. This includes collecting data on the number of flights operated, the number of passengers carried, and the impact on local economies. This data is used to evaluate the scheme's performance and to make adjustments as needed. This ensures that UDAN remains relevant and effective in achieving its goals.

UDAN aims to improve regional connectivity not just through air travel, but also by integrating it with other modes of transportation, such as roads and railways. This includes developing intermodal transportation hubs that allow passengers to seamlessly transfer between different modes of transport. This integrated approach helps to create a more comprehensive and efficient transportation network.

A potential challenge with UDAN is the long-term sustainability of the routes once the initial subsidy period ends. Airlines need to develop strategies to make these routes profitable on their own, such as increasing passenger loads and reducing operational costs. The government is also exploring ways to support airlines in this transition, such as providing additional incentives or extending the subsidy period.

UDAN is different from previous attempts to boost regional aviation because it uses a market-based approach with competitive bidding and Viability Gap Funding. Earlier schemes often relied on direct government intervention and lacked the flexibility to adapt to changing market conditions. UDAN's approach is designed to be more efficient and sustainable in the long run.
