Thank you so much! I realized I have a question about the return flight as well:

The tickets were booked through Qatar Airways all on one ticket. The flights to New Delhi are both Qatar Airways. The return flights (booked through the same booking through the Qatar Airlines website) New Delhi->Doha is a partner carrier Indigo, and Doha->Atlanta is Qatar Airways. In that case, would we need to retrieve our checked bags and go through customs & security? Our connection time is 2 hours. If so, would we benefit from using the gate concierge service?
