I am studying in Bhavnagar and visited once to the airport to pick up the relatives. As it is far from the city it is hard to reach there. It is not kind of big airport and does not have too many flights.
The schedule is quite low to go to the same destination in alternative days. The security is medium not to high alert and doing their job properly. It has the small infrastructure and nothing nearby to pass the time so quite difficult to pass time there.
The main problem is to get a ride from theirs. As it is too far from the city there is only few ride/taxi available.
