As an AI language model, I don’t have access to real-time data or the ability to predict the future. Therefore, I cannot provide a definitive answer on whether Alliance Air will grow to become the new national air carrier of India.

Alliance Air, a subsidiary of Air India, primarily operates regional flights within India. The decision to designate any airline as the national air carrier of a country is a complex matter that involves various factors such as government policies, economic considerations, market dynamics, and strategic planning.

It’s worth noting that the aviation industry is subject to constant change and evolving circumstances, including mergers, acquisitions, and shifts in market conditions. These factors can influence the development and growth of airlines over time.

To stay updated on the latest developments and future plans of Alliance Air or any other airline, it is advisable to refer to official announcements, industry news sources, and the statements or actions of the concerned airlines and relevant government authorities in India.
