India is a big enough country that "flights to India" really means picking the right city first — the routing, airlines, and even the best booking window can shift depending on which gateway you're flying into.
The main gateway airports
Delhi (DEL) and Mumbai (BOM) are the two largest international gateways and carry the most US flight options, followed by Bengaluru (BLR), Chennai (MAA), Hyderabad (HYD), and Kolkata (CCU). If your final destination isn't one of the biggest cities, you'll likely connect once more domestically within India after your international flight lands.
Routing options from the US
- Nonstop service exists on select routes, mainly to Delhi and Mumbai from a handful of major US hub cities — confirm current nonstop routes from your specific home airport, since these change over time.
- Connecting via the Gulf (Doha, Dubai, Abu Dhabi) is one of the most common one-stop options, with strong onward service to nearly every major Indian city.
- Connecting via Europe (London, Frankfurt, Paris, Amsterdam) is another well-served option, particularly useful if your home airport has strong service to that European hub.
When to book
Demand spikes hard around Diwali, major wedding season months, and the summer travel period when the Indian diaspora visits family — booking 3–6 months ahead for those windows makes a real difference in both price and seat availability. Outside peak periods, 2–4 months ahead is usually enough for a long-haul international itinerary like this.
What to plan for
- Visa requirements — most non-Indian passport holders need a visa or e-visa; apply well before your trip and confirm current requirements, since policies change.
- Domestic connections — if you're headed beyond Delhi or Mumbai, book your India-domestic connecting flight with enough buffer time after a long-haul arrival, especially if it's on a separate ticket.
- Total travel time — even with a "good" connection, expect 16–22+ hours door to door depending on your home airport and routing.
Why this route benefits from a phone comparison
With several genuinely different hub options (Gulf carriers, European hubs, and limited nonstop service) and an extra domestic leg for many travelers, comparing total itinerary time and connection quality across options is easier with someone searching several combinations for you at once.
