Hello
I am planning to fly an IAD-DEL-AMD on a single PNR. IAD-DEL is on AI, and DEL-AMD is also on AI with 9 hours Layover in DEL.
my question is,
1) can I check in as soon as I clear the custom, which will be at least 8 hours in advance for my connecting domestic flight?
2) once I checked in, can I exit the airport and check out of the city and come back closer to the departure time?

Thanks
