Terminal 1

Qantas, Jetstar Asia and Philippine Airlines all check in at T1

Terminal 1 at Singapore Changi handles Qantas, Jetstar Asia and Philippine Airlines, and links airside to T2 and T3 without extra security. That link is the real story here: after landing at a T1 gate, many through‑passengers head straight for the Skytrain to T2/T3 or walk the concourses in under 10–15 minutes to reach other lounges and transit hotels.

Airside layout and moving between T1, T2 and T3

The T1 departures concourse sits between gates in the C and D pier zones, with walkways feeding directly into the connectors for Terminal 2 and Terminal 3. Airside, you can walk from a T1 gate to a T3 gate in roughly 10–20 minutes depending on your pace, or use the Skytrain that runs every few minutes between the terminals, all without re‑screening. One FlyerTalk user planning a transit hotel stay says it “doesn’t really matter” which of the three terminals you arrive at, because the airside link makes the transit hotels and lounges effectively shared.

Lounge options: four in T1 plus easy access to others

Inside T1 you get the Qantas Business Lounge, SATS Premier Lounge, Plaza Premium Lounge and DNATA Lounge, all past immigration. The Qantas Business Lounge typically opens in the afternoon to sync with QF metal departures to Sydney and Melbourne, while Plaza Premium and SATS usually run longer hours into the late night to catch Jetstar Asia and regional traffic. Regulars with long connections often check crowding and access rules, then walk over to a T3 KrisFlyer lounge or a T2 transit hotel instead, using T1 more as a cross‑corridor than a base.

Food: noodles, burgers, sushi and kopi under one roof

For a quick meal between flights, T1 has Crystal Jade La Mian Xiao Long Bao near the main transit mall, Sushi Tei on the airside dining level, plus global chains like Burger King and Subway near several gate clusters. A typical bowl of la mian or a basket of xiao long bao at Crystal Jade runs around SGD 10–15, a Burger King meal hovers near SGD 10, and kopi with kaya toast at Toast Box or Heavenly Wang is usually under SGD 7. Harry’s Bar adds late‑evening drinks and bar snacks near some of the C‑gates, handy if you’re waiting on a Qantas red‑eye.

Shopping: duty free anchors plus a few brands

Shilla Duty Free sits in the central transit zone with liquor, cosmetics and fragrances at duty‑free pricing that often undercuts downtown Singapore by several dollars per bottle. You’ll also see Watsons for pharmacy and travel‑size toiletries, WHSmith for books and snacks near some departure clusters, and fashion and accessories like Chanel Beauty and Longchamp. If you want a specific brand that is missing in T1, the airside walk to T3’s bigger luxury line‑up can be under 10 minutes from the central T1 atrium.

What regulars actually do with a long layover

Flyers who know Changi land in T1, clear to the airside mall in under 10–20 minutes, then head straight for other terminals if they’re chasing a quieter lounge or a cheaper transit hotel rate in T2 or T3. Many report timing the walk from a T1 gate to a T3 transit hotel at around 15 minutes including escalators and moving walkways. If web maps are blocked on office or hotel Wi‑Fi, frequent FlyerTalk contributors recommend opening the Changi Airport mobile app for zoomable gate‑level maps of T1/T2/T3 instead of squinting at static boards.

One thing to watch and one tip

Watch your walking time if you plan a lounge hop before a Qantas or Jetstar Asia departure from a far C‑ or D‑gate; a 12‑minute stroll back from a T3 lounge plus boarding checks can eat into your margin. Best move: download the Changi Airport app before you land, pull up the live T1/T2/T3 map as soon as you’re on Wi‑Fi, and plan your path from your exact T1 gate to food, shops, lounges or another terminal before you start walking.
