I will be travelling from Kolkata to Chicago via Doha. There is 1 hour overlay for the flight for Doha to Chicago. Is this 1 hour time enough. I see that both the flight QR547 and QR721 will be leacing from Terminal 2. Does it mean that there won't be any security check and that I need to offboard QR547 and then board QR721 again from the same terminal. I will be travelling this weekend, so please do help me out.
This is my first travel to US, so can someone please help me out regarding this. I will be booking my luggage as through luggage.
