I agree Metro connectivity is a must to all airports..I'm glad my home base is connected with a metro..But I guess not all Indian airports are connected I can think of Delhi,Chennai and my base ..may be CCU don't know for sure..I'm sure BLR and HYD are not connected for sure which I think is a huge disappointment and should be connected asap !
Oh and also not sure about your base MrPNQ...any gov plans to connect it with Metro anytime soon ?
I would like to be corrected, the last time I had been to Delhi there was no direct connectivity in the airport. The last time I went was in 2019. You have the stop at Delhi Aerocity from which you need to take the bus to the terminal. Mumbai is supposed to have one. https://en.wikipedia.org/wiki/Line_3_(Mumbai_Metro
The other one which I know which has a metro right up the airport is kochi airport but I haven't had a chance to use it. The last time I was in Kochi was in 2018 and was steered around by people both on the way in and back. The Kochi Metro would probably expand and needs to expand as much as Delhi Metro if it wants to as ubiquitous as the Delhi one is. I think the Delhi metro is the gold standard which other cities having metro should pine for. Mumbai may soon though give a run for its money even though Delhi has a 20 year old headstart.
Anyways, enough of rambling for now. Almost all new and old airport do need these metros to make travel easier, lighter etc.
As far as the question of Pune is concerned, no chance at least for next few years. The problems are mani-fold. First, the airport itself is half military and half-civilian, so nobody including air force people would want more commercialization. Also if people have looked at the PNQ airport it is located very weirdly. There had been no planning done at all but then this was not supposed to be a civilian airport. Also the recent recarpeting work had many hassles for the flying public.
That recarpeting work had started in April 2020 and till December 2020 was not completed. Why, I have no clue. https://timesofindia.indiatimes.com/cit ... 034641.cms
So, if they can't do that, then asking them to pay for a station or two would be going overboard. There are suggestions from citizen groups to have a metro extension all the way to Pune Airport. You would want to have 24x7 services as many cheap domestic flights come at red-eye times, around 0200 or 0300 hrs.
Demands from citizens and politicians for extensions of the same - https://www.thebridgechronicle.com/pune ... ease-46712
