Honestly a real shame, it gave a lot of reach to QF and really make SIN into a hub that not many other airlines have overseas in this day and age.
That being said with Scoot constantly rising, Airasia and all the other lowcost airlines in the region from T’way, Zipair, GBA, Vietjet etc its increasingly harder for them to compete for a pie that whilst growing again had shrunk so much due to covid.
For SIN based QFFs it was great to have lounge access and I always had a soft spot for the OKA route as it allowed through ticketing to KIX and NRT with Jetstar japan.
Part of SGN being dropped is maybe also due to the demise of Jetstar pacific.
Agreed, although the market and QF have changed so much since its establishment. Consider that within a few years after its establishment, QF were routing daily SYD-SIN-LHR, MEL-SIN-LHR and SYD-FRA-FRA through SIN, supplementing it with connecting PER-SIN, BNE-SIN and ADL-SIN. JQ were also feeding CNS-SIN, DRW-SIN, MEL-SIN and PER-SIN. In addition, BNE extended onto BOM! So SIN was in a good position to feed to and from additional regional routes, and advance from being a scissor hub.
But the world and market changed entirely. They dropped FRA and switched LHR flights to DXB. The ADL flight and extension to BOM was dropped. Scaled up SYD-CGK and SYD-MNL over time. All this reduced the critical mass and couldn't be supplemented by connecting traffic from third party airlines which they had less control of capacity and revenue management.
A point you highlight is that 3K was never able to build a legitimately independent low cost operation that could compete. Like Scoot (and Tiger) they could not really compete with AirAsia, Lion, Batik Air, Cebu Pacific, IndiGo, VietJet Air, etc who will always beat Scoot, Tiger and Jetstar Asia on cost structure. Even SQ folded Tiger into Scoot, and Scoot has been a mechanism for SQ to shift its own cost base.
