AD PLACEMENT — CONTEXTUAL
Budget extra time if your connection requires moving between the domestic and international terminals, as the walkway can be crowded and slow.
International arrivals connecting to a domestic flight must clear immigration and customs before re-checking in, so this is one of the slower transfer types.
Signage can be inconsistent, so ask ground staff early rather than relying on airport displays.
If both flights are on the same PNR with an airline like IndiGo or Air India Express, staff at the transfer desk can often expedite you through security.
Avoid tight connections during late-night and early-morning banks (11pm-3am) when Middle East and Southeast Asia flights cluster and lines lengthen.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Passengers move between the Anna International Terminal and the Kamaraj Domestic Terminal via a covered walkway that can take 15-20 minutes on foot, longer at peak times due to crowding and queues. Some transfers, particularly those involving the newer integrated terminal building, require a shuttle bus across the apron, and all international-to-domestic and domestic-to-international transfers require full re-screening and, for arriving international passengers, an immigration and customs process even when only connecting.
