For India you typically need a valid passport and the correct Indian visa before departure unless the airline and Indian rules say otherwise that day. Delhi (DEL) is the published route. A ticket is not a visa. Start /services/visa-india before non-refundable fares. Connecting beyond Delhi is covered in /guides/transit/del. Rules change. Confirm visas, transit, and baggage with the airline and the relevant embassy before you travel. Is this legal advice? No. It is how Sharifi Neya frames documents for ticketing. Governments and airlines can impose extra checks the same day.
