Jamshedpur managed so many Cricket Games. (One day Internationals). I wonder how Gangtok got nod as Bagdogara airport is far. Also many teams fly to Guwahati airport and then go by road to Shillong. JCT Club was playing at Ludhiana with not so regular Air service. Kolhapur was venue of ONGC, Air India, Mumbai FC without airport.
Tier 2 cities airport is massive failure in India and I don't see AIA investment any further. It is big burden, we aren't yet ready for aviation domestically. Mysuru airport is dusted!!! and many other.
In last 10-15 years, aviation has improved a lot in India. Growth rate of passengers every year is high. Our airports are now much better then before. Look at growth rate of passengers every year
