Direct (nonstop) flights from Hartsfield–Jackson Atlanta International Airport (ATL) to Indira Gandhi International Airport (DEL) are uncommon or seasonal; most travelers fly connecting itineraries. Connecting flights often save money and open more schedule options, but add layover time and transit complexity. If minimizing travel time is your priority, choose the shortest total journey even if it costs more; if saving money matters, pick reputable one-stop carriers via Doha, Dubai, Istanbul, London, or Frankfurt. Check transit visa rules for your chosen hub and allow at least 90 minutes for international transfers.
