Will have multiple domestic connection coming up in a few weeks through different airports, such as DEL, BOM, CCU etc.

What is the general transit process when it comes to domestic flights? Is it set up like in the US where departing/arriving passengers are not segregated, meaning you disembark into the departure area avoiding another security check?

For instance at CCU I am looking at a 1 hour connection on separate tickets, but with no bags. Is that enough time?

Are all airports set up in such a way you have to go through security again? Are some airports better at domestic transit than others?


Appreciate all kind of information!
