Singapore Changi Airport has recently reopened its largest passenger facility – Terminal 2 – following a significant spike in passenger traffic recovery over the last couple of years, which has seen many airlines either returning to the terminal or operating from there for the first time.

These have included the likes of Ethiopian Airlines, Lufthansa, Swiss, United and ANA, and now there’s news of another Star Alliance carrier making the switch.

Thai Airways is moving to T2

Thai Airways has announced that effective from 18th February 2025, it will be operating to and from Terminal 2 at Changi Airport, a shift from its long-term home in Terminal 1.

Thai Airways is stating that check-in will be at Row 8, however the airline is also saying this is near to departure drop off Doors 3 and 4 – which doesn’t seem right. Row 8 is actually adjacent to departure drop off Door 6.

Check the Changi Airport website closer to the switchover date, which should provide accurate information.

Thai Airways’ Singapore schedule

Thai Airways currently operates 35 weekly flights between Singapore and Bangkok, which equates to five daily services to and from Suvarnabhumi Airport (BKK).

Here’s how the schedule looks in February 2025, following the airline’s move to Terminal 2.

This schedule represents a full return of Thai Airways’ original pre-pandemic flights at Singapore Changi Airport.

The lounge situation

The move from Terminal 1 to Terminal 2 means some changes for Thai Airways passengers when it comes to the pre-flight lounge situation.

As many of our readers may remember, the airline previously had its own (small) lounge at Changi Airport T1, which was the sole Star Alliance facility in that terminal.

However, the lounge closed temporarily during the COVID-19 pandemic, and even once travel recovered again the airline decided not to reopen it, as we reported in February 2023.

Since then, the airline has been offering Business Class passengers and Star Alliance Gold travellers departing in any cabin on its flights access to the Marhaba Lounge in Terminal 1 (see our review), and we expect the airline will direct passengers to the SATS lounge in Terminal 2 following the move.

What ‘in the know’ eligible passengers on Thai Airways should probably do is use the far superior lounges of Star Alliance partner Singapore Airlines, which includes the latter carrier’s latest facilities in Terminal 3, though this involves a SkyTrain ride after clearing immigration.

• Business Class passengers can access the Singapore Airlines SilverKris Business Class lounge
• KrisFlyer Elite Gold passengers can access the Singapore Airlines KrisFlyer Gold lounge (+1 guest travelling on the same flight)

Thai Airways passengers will be able to use the reopened KrisFlyer Gold Lounge and SilverKris Lounges in Terminal 2 once the switchover takes place, though those pale in comparison to the newer T3 facilities.

Nonetheless, there’s always the option to hop on the SkyTrain and take a 10-minute journey across to the newer SIA lounge facilities in T3 from 18th February 2025 onwards, an even easier journey than it is to these lounges from T1.

We have recent reviews of the refreshed T2 KrisFlyer Gold and SilverKris Business Class lounges since they reopened back in October 2022, with some minor enhancements but more or less with the same dated format they had pre-pandemic.

In this case, the KrisFlyer Gold lounge is for Star Alliance Gold members departing on Thai Airways in Economy or Premium Economy Class, while the SilverKris Business Class lounge is for those departing in Business Class.

For those using Priority Pass or similar lounge access programme before departure, the selection in Terminal 2 is a little more sad and tired that that in Terminal 1 (including the SATS Premier Lounge, in our opinion).

On the flip side, there is a wider range of non-lounge food and spa redemption options using your Priority Pass in T2, as we recently covered in detail, including a fixed S$33.50 off the F&B bill at Asian Street Kitchen.

Award rates

Thai Airways can be a great alternative to Singapore Airlines on the Bangkok route for KrisFlyer members, either when award space is not available for your preferred date on SIA, or if you just fancy a change.

These are the KrisFlyer miles needed to redeem Singapore – Bangkok flights on Thai Airways (Star Alliance award).

KrisFlyer Redemption Singapore ⇄ Bangkok
	Star Award
Economy	13,500
Business	24,000

Do note that Thai Airways passes on some fuel surcharges with its award tickets, so despite the miles redemption rate being the same as it is for SIA flights on this route, the cash outlay is higher.

Which airlines are now using T2?

Thai Airways will become the 21st carrier to operate from Terminal 2 at Changi Airport following its post-COVID-19 reopening, joining recent additions including Peach and Starlux.

Here’s the full list of airlines operating from Changi Airport Terminal 2, in order of commencing operations at the reopened terminal following its two-year closure.

* Post T2’s COVID closure, for returning carriers

In total, T2 will handle 913 passenger flight departures per week (an average 130 per day), based on February 2025 flight schedules, its busiest since post-pandemic reopening.

T2 is now the largest at Changi Airport

As most of our readers already know, Changi T2 recently had a full makeover, which CAG says now boasts a “contemporary design concept… inspired by elements of nature”.

Enhancements in the transit area include new dining concepts in a larger space, with better views of the runway.

T2 is now the airport’s largest terminal, stealing T1’s thunder with a capacity for 28 million passengers per year – 5 million more than pre-renovation.

Capacity of Changi’s Terminals (2020 – 2025)
Terminal	Capacity 2020	Capacity 2025
T1	24m	24m
T2	23m	28m
T3	22m	22m
T4	16m	16m
Total	85m	90m

A significant 15,500 square metres has been added to the terminal’s original floor space, and the revamp has boosted Changi’s annual passenger capacity to 90 million.

This will secure the airport’s passenger operations through to the opening of Terminal 5, in the mid-2030s.

Star Alliance carrier Thai Airways is set to be the 21st airline to operate from Singapore Changi Airport’s new renovated Terminal 2, shifting its five-times-daily Bangkok services across from Terminal 1.

It’s good news for T1 crowding (and lack of gates at peak times), plus eligible Thai Airways passengers will now have easier access to the SilverKris / KrisFlyer Elite Gold facilities in T2, though they have only had a minor revamp during the pandemic.

Luckily there remains the option to duck across to T3 on the SkyTrain and use SIA’s latest lounges there, provided you build in an additional 15 minutes or so to reach your T2 departure gate come boarding time.

T2 is now largest of all the terminals at Changi Airport, until the behemoth Terminal 5 opens in the mid-2030s.
