As Terminal 2 at Changi Airport gears up for its complete reopening next month, two additional airlines are slated to relocate their operations to alternative facilities within the airport in the weeks ahead.
One noteworthy development is the return of Vietnam Airlines to Terminal 3, marking the first time in nearly six years, apart from the period necessitated by the airline’s temporary relocation to T4 during the pandemic-induced closure.
Subsequently, the following week will witness Etihad Airways reverting to its customary Terminal 2 domicile, coinciding with the resumption of its daily flight to Abu Dhabi, all while ANA makes its return to T2.
Effective September 26, 2023, Vietnam Airlines will relinquish its longstanding Terminal 4 slot in favor of a move to Terminal 3. Then, commencing on October 5, 2023, Etihad Airways will reoccupy Terminal 2.
This realignment is likely to be one among several anticipated shifts in the forthcoming months, as the full reopening of Terminal 2 will grant it the highest capacity of any facility within the airport.
Vietnam Airlines T4 to T3
Effective from 26th September 2023, Vietnam Airlines will be moving out of Terminal 4 and operating to and from Terminal 3 at Changi Airport.
This one is a little unexpected – Vietnam Airlines was one of the first carriers to move to Terminal 4 when it originally opened, shifting from T3 to the brand new terminal on 7th November 2017.
The airline temporarily ceased Singapore flights from March 2020, due to the COVID-19 pandemic, but returned to Changi in 2021, operating under Singapore’s Vaccinated Travel Lane (VTL) programme three days per week to and from Hanoi and four times per week to and from Ho Chi Minh.
These flights used Terminal 3 at Changi Airport, due to the temporary closure of Terminal 4, however the airline moved back to T4 a week after its reopening – on 22nd September 2022.
This move will see the number of full-service carriers operating at Terminal 4 reduce from four to three, with only Cathay Pacific, Korean Air and Juneyao Air falling into this category from 26th September 2023.
T4’s seven other airlines are low-cost carriers, including AirAsia and Jetstar.
Once Vietnam Airlines moves out, Changi Airport Terminal 4 will continue to see 581 weekly flight departures, as shown below.

Changi Terminal 4 is currently operating at around two-thirds of its annual 16 million passenger capacity, so there is room for existing carriers to expand, or for some new airlines to establish operations there or move across from existing terminals.
Vietnam Airlines currently operates 35 arrivals and departures per week at Changi, 14 per week to and from Hanoi and 21 per week to and from Ho Chi Minh, using Airbus A321 aircraft, as shown in the schedule below.

The final Vietnam Airlines departure from Terminal 4 will be VN656 to Ho Chi Minh at 8.45pm on 25th September 2023. Subsequently, all the carrier’s arrivals and departures at Changi will be processed through Terminal 3.
Eligible LotuSmiles Gold and Platinum members and Business Class passengers will be directed to use the SATS Premier Lounge in T3.
Vietnam Airlines’ low-cost subsidiary Pacific Airlines (formerly Jetstar Pacific) will continue to operate four times weekly Singapore – Ho Chi Minh flights to and from Terminal 4, including Vietnam Airlines codeshare service.
Luckily the five daily Vietnam Airlines flights at Changi fall mostly outside Terminal 3’s peak periods, which we recently identified means around 10 Singapore Airlines T3 flights need to use Terminal 1 gates each day.
Only the VN657/656 service operates at a peak timing, occupying a gate from 7.15pm to 8.45pm, but luckily a similarly-timed Etihad T3 departure will be relocating to a different terminal just a week later.
Etihad Airways T3 to T2
From 5th October 2023, Middle East carrier Etihad Airways will relocate its daily Singapore – Abu Dhabi flight from Terminal 3 back to the airline’s former home at Changi in Terminal 2, the same day that All Nippon Airways makes a T1 > T2 switch.
Here’s how Etihad’s Changi Airport schedule looks.

The final Etihad Airways flight to arrive into Terminal 3 will be EY470 from Abu Dhabi at 9.55am on 4th October 2023, with the final T3 departure that same evening as EY473 to Abu Dhabi at 8pm.
From EY470’s arrival on 5th October 2023 onwards, Terminal 2 will be used to process all arriving and departing Etihad flights at the airport.
Eligible passengers departing on Etihad flights will be invited to the SATS Premier Lounge in Terminal 2.
Etihad will be the 14th airline to operate from Terminal 2 following its post-COVID-19 reopening, joining recent additions like Ethiopian Airlines, Malaysia Airlines and United Airlines.
Here’s how the operator list looks as of 5th October 2023, in order of commencing operations at the reopened terminal following it’s two-year closure.
