Terminal T1 hosts 3 airlines.
One integrated building now handles CCU domestic and international
For about 10+ years, Kolkata’s Netaji Subhash Chandra Bose International Airport has run domestic and international flights out of a single integrated terminal, so the so‑called “Domestic Terminal” is really the domestic side of that building, not a fully separate facility. SpiceJet, Go First and AirAsia India all check in and depart from this domestic section, alongside other Indian carriers using the same shared halls.
Terminal 2 (often just called the integrated terminal) covers both domestic and international operations, so if an itinerary or agent still mentions a separate domestic terminal, read that as the domestic zones of T2. The old T1 building used for domestic departures is largely out of regular passenger use, and current FlyerTalk reports point to everything funnelling through the combined T2 structure.
Check‑in for SpiceJet, Go First and AirAsia India sits on the domestic side of the main departures level, with counters grouped by airline and flight number on overhead screens. Security for domestic flights then feeds into a dedicated domestic pier with multiple boarding gates, so a SpiceJet flight to DEL and an international flight to DXB never share the same waiting area, even though both sit inside T2.
Post‑security in the domestic section, food and shopping details are thin in public documentation, and no specific restaurants, lounges or duty‑free outlets are reliably catalogued by gate or brand name. That lines up with online trip reports, where regulars talk about the integrated setup at CCU but rarely list specific domestic‑only venues by name, unlike airports where each pier has clearly marketed chains.
Lounge options tied specifically to the domestic side of CCU’s integrated terminal also go largely undocumented, with no clearly branded domestic lounge names surfacing in newer reports. Some older references to separate domestic and international lounges pre‑date the full shift into T2, so treat any mention of a “Domestic Terminal lounge” without a gate or level number as likely outdated.
Because CCU’s domestic and international operations sit in one building, connections between a SpiceJet domestic leg and an international flight can avoid any inter‑terminal transfer, saving the 10–20 minutes you might lose at airports that still run T1/T2 as different structures. One regular on FlyerTalk explicitly notes that CCU international and domestic have been in one terminal for about 10 years, and current connection reports back that up.
What regulars do: they ignore references to a separate domestic terminal when planning, and just budget time for normal T2 check‑in, security and a walk to the gate. The practical move is simple: arrive 2 hours before a domestic departure on SpiceJet, Go First or AirAsia India at CCU, head straight to Terminal 2 departures, and follow the domestic flight signs rather than hunting for a non‑existent standalone Domestic Terminal.
