I am an Indian citizen travelling from Istanbul to Kolkatta. I have booked with Turkish Airlines. My Istanbul-Delhi leg is with Indigo and I arrive Delhi at 0500 hrs and then my Delhi-Kolkatta leg is with AirIndia departing at 1400 hrs. The entire journey has a single PNR.
My want to know if it is possible to exit the Delhi Airport for the duration of my transit? Is their like a special procedure to be followed to that?
