banger2 makes a very interesting point there, Scoot is still selling seats for flight TZ1 SYD-SIN direct on the 30th May (about AUD$249 on the Scoot.com.au site). If the OP post from bignbeefy is correct and scoot called them saying that the flight is cancelled sort of raises the following questions.
Given that the scoot booking site around the 30th May is still showing 6 services a week between SYD-SIN, how can that be reconciled with what flyingdouble is seeing? If markis10's questions about the route under-performing are correct (and the airfares offered by scoot around that period would suggest that is true), are we just seeing Scoot putting seats on the market, seeing which days fill up, and then moving pax from the lowest loading flights forward or backwards by a day? What are the legal implications of selling a seat for a service destined to be cancelled or re-timed to +/- 48hours?
If so - a demand for full cash refund should be honoured, correct? Obviously this would be unsuitable for people with connections, any important events/meeting to attend, or indeed any "dealbreaking" timing issues.
Are we actually seeing a return to the standby/Laker Long haul LCC economic model?
