Flying Air India out of Delhi's Terminal 3 on a domestic route? There's a dedicated lounge airside that's worth knowing about — comfortable, open around the clock, and stocked with hot Indian food — though it comes with one notable gap: no alcohol whatsoever.
The lounge sits on the mezzanine level of Terminal 3's domestic departures area. After security, follow the airline lounge signs up from the shopping area before you reach the gates. It's open 24/7, so even a brutally early departure is covered.
Access follows standard Star Alliance rules. Business and first class passengers get in, as do Star Alliance Gold members regardless of which cabin they're flying on a Star Alliance departure — that includes Air India's Maharaja Club Gold and Platinum tiers. In practice, that means a Gold status holder in economy can walk right in, which is a decent perk on India's busy domestic trunk routes.
Inside, the seating mix is tables with chairs and benches, with power not guaranteed at every spot. The beige armchairs, however, come with universal outlets plus USB-A and USB-C ports, so grab one of those if you need to charge. Wi-Fi runs off the airport network rather than a dedicated lounge login — you'll need a mobile number to connect, or the front desk can hand you a slip with a code. The reviewer found it easy to get online and productive, though a short visit left long-session performance untested.
The food is the real draw. There's a generous spread of hot and cold Indian dishes alongside breads, rice, salads, snacks, fruit and desserts, plus coffee machines, tea, soft drinks and juices. Showers are available too, and the restrooms — while crowded during the visit — were clean.
The catch: this is a dry lounge, and domestic flights in India are dry as well, so no pre-flight beer. It's also worth flagging that this isn't Air India's flagship Maharaja Lounge, which lives in the international departures area. The two aren't connected, and the swankier international lounge is only accessible when leaving India, not arriving.
Who is this for? Anyone with Star Gold status connecting through Delhi domestically, or business class passengers on Air India's dense Delhi–Mumbai corridor, will find it a genuinely useful wait spot — the reviewer notes the domestic side of T3 otherwise has little to recommend it. That said, the verdict was measured: a pleasant place to pass time before a flight, but not somewhere worth arriving early for. One traveller even cut the visit to 15 minutes for the chance to fly Air India's A350-900 instead — a swap they considered well worth it.
If you're transiting Delhi on a domestic itinerary, plan around the strengths: eat a proper meal, take a shower, charge your devices, and save the drinks for your destination.
