Do international travelers need an Indian visa for an airside transit in Delhi when flying onward to Kathmandu?

When connecting to Kathmandu via Delhi, travelers can usually remain in the international transit area and proceed directly to the next departure gate. In this case, there is no need to clear Indian immigration or obtain a visa.

Visa-free airside transit is possible when the connection does not require a terminal change. Check the Delhi airport terminals for both flight segments before booking or checking in.

If checked luggage is tagged through to Kathmandu, it does not need to be collected in Delhi, allowing travelers to remain airside. Collecting and rechecking baggage would require entering India and therefore a visa.

Even for an airside connection, the airline operating the first flight may request documents confirming eligibility to board and continue onward. Confirm whether a validated Delhi–Kathmandu ticket is sufficient or whether an electronic entry authorization is required.
