Changi Airport Terminal Guide: Which Terminal for Which Airline

← Home

The Changi Airport terminal guide question that matters most is the one people get wrong: Singapore Airlines does not fly from a single terminal, and neither does much of the rest of the alliance map. Four terminals sit around a common Skytrain loop with Jewel in the middle, and knowing which one applies saves a wrong turn at the taxi rank or MRT gate.

Changi Airport Terminal Guide: Terminal 1

Terminal 1, Changi’s original terminal from 1981, handles a broad mix of full-service carriers — Scoot, Japan Airlines, Air France, KLM, Qatar Airways, British Airways, Emirates and Bangkok Airways among them. It’s built around a “Tropical City” theme with the Kinetic Rain sculpture in the departure hall and a rooftop pool for transit passengers, and it’s the closest terminal to Jewel — about a five-minute walk.

Terminal 2: Where Singapore Airlines Splits Off

Terminal 2 reopened fully in November 2023 after a multi-year redevelopment and now carries a chunk of Singapore Airlines’ regional network — flights to Southeast Asia, Colombo, Dhaka, Kathmandu, South Korea and Japan — alongside Lufthansa, SWISS, ANA, Thai Airways, Air India, Etihad, United and Air Canada. Singapore Airlines has continued investing here, including a 2025 overhaul of its T2 lounges, so this isn’t a secondary terminal for the airline — it’s a genuine second hub alongside Terminal 3.

Terminal 3: Singapore Airlines’ Long-Haul Hub

Terminal 3 carries the rest of Singapore Airlines’ network — Northeast Asia, India, Australia, New Zealand, Europe, the US and African routes — plus Garuda Indonesia, Eva Air, Asiana, China Eastern, China Airlines, Vietnam Airlines and Batik Air. It’s built to handle the Airbus A380 and holds two attractions in its own right: The Slide, a four-storey slide inside the terminal, and a Butterfly Garden with over 1,000 tropical butterflies. It’s also the terminal furthest from Jewel by walking distance, at roughly ten minutes.

Terminal 4: The Budget and Regional Terminal

Terminal 4, opened in 2017, runs as a single compact concourse for AirAsia, VietJet Air, Jeju Air, Cebu Pacific, Korean Air, Cathay Pacific and Jetstar. It isn’t connected to the Skytrain loop the other three share, so getting to Jewel or between terminals means the free shuttle bus. The Petalclouds kinetic sculpture, suspended above the departure hall with synchronized lighting, is its answer to Terminal 1’s Kinetic Rain.

How the Terminals Connect

Terminals 1, 2 and 3 share a free Skytrain that also connects to Jewel; Terminal 4 is reachable only by shuttle bus. Because airlines do occasionally shift terminals — Terminal 2’s 2023 redevelopment moved several carriers around, and further shuffles happen as routes change — the boarding pass or airline confirmation is the only source that’s guaranteed current on any given day, more reliable than any published terminal list, including this one. For where to stay close to any of the four, see the best airport hotels at Changi and the guide to Jewel Changi Airport in the middle of them all.

Frequently Asked Questions

Which terminal does Singapore Airlines use?

Both Terminal 2 and Terminal 3, split by route — regional Southeast Asian and a handful of Northeast Asian routes from T2, most long-haul from T3. Always check the specific flight.

Which terminal is Scoot?

Terminal 1, alongside most of the other full-service international carriers based there.

Do I need to check my terminal before heading to the airport?

Yes — terminal assignments shift as airlines move and terminals get redeveloped, so the boarding pass or airline app is the only reliably current source.

Which terminal is closest to Jewel Changi Airport?

Terminal 1, about a five-minute walk. Terminal 3 is the furthest of the Skytrain-connected terminals at roughly ten minutes.

Bottom Line

Terminal 1 covers a broad mix of full-service carriers, Singapore Airlines splits across Terminal 2 and Terminal 3, Terminal 4 handles budget and regional airlines off the main Skytrain loop — and every terminal connects to Jewel in the middle.
