I am an Indian citizen travelling from Istanbul to Kolkata. I have booked with Turkish Airlines. My Istanbul-Delhi leg is with Indigo and I arrive in Delhi at 05:00. And then my Delhi-Kolkata leg is with Air India departing at 14:00. The entire journey has a single PNR.
Is it possible to exit Delhi airport for the duration of my transit? Is there like a special procedure to be followed for that?
