Earlier this month, Changi Airport Group (CAG) announced that it was suspending operations at Terminal 2 for 18 months, due to the dearth in air traffic caused by Covid-19. In the same statement, CAG also added that it was considering suspending operations at Terminal 4. In their words:
If the remaining airlines at T4 choose to suspend or adjust their flight schedule, CAG will also consider suspending operations at T4 temporarily but with the objective of restarting operations quickly when airlines confirm the resumption of flights.
It appears a decision may already have been madeโฆ
Cathay Pacific is shifting operations to Terminal 1
Cathay Pacific sent an email to its customers today informing them that it will relocate to Changi Terminal 1 from tomorrow, Thursday, 16 April 2020.

Cathayโs website has also been updated to reflect this change:
This means the Cathay Pacific Lounge in Terminal 4 will be closing indefinitely, although I doubt anyoneโs going to miss it at the moment. Cathay Pacific passengers at Terminal 1 will be invited to the dnata lounge instead.


For what itโs worth, Cathay Pacific has already drastically cut capacity out of Singapore, with just five flights scheduled for the rest of April.
The schedule picks up a bit in May with three flights per week scheduled, but it remains to be seen if these actually operate, given all thatโs going on.
Terminal 4 will almost certainly suspend operations

The following airlines currently operate out of Terminal 4, at least on paper:
- AirAsia
- Cebu Pacific Air
- GoAir
- GX Airlines
- Hainan Airlines
- Jeju Air
- Juneyao Airlines
- Korean Air
- Regent Airways
- Spring Airlines
- Urumqi Air
- Vietjet Air
- Vietnam Airlines
In reality, virtually all of them have suspended flights to Singapore, and there just isnโt a whole lot happening at Terminal 4 these days. A brief glance at tomorrowโs departures shows just two flights scheduled on Juneyao Airlines, and itโs doubtful theyโll even happen, given that there werenโt any departures from Terminal 4 today or yesterday.
So Cathayโs departure must surely be the nail in the coffin (or perhaps more accurately, CAG already made the decision to close Terminal 4 and hence relocated CX), and I expect weโll get an announcement very soon.
Conclusion
It seems virtually certain that Changi Airport will now operate just two terminals, something I never dreamed Iโd write. In the cold light of day, however, it just makes sense. With so few flights, why would you incur the utilities and manpower expense to run a virtual ghost town?
I suppose the good news is that Terminal 4โs suspension is likely to be much shorter than Terminal 2โs, and once air traffic picks up again weโre likely to see operations resume rather quickly.
We hope, we pray.
