I wouldn't touch them using Scoot ticket. No way.
However, they seem to be using Scoot for economy fares into Oz from SIN, instead of SQ (the only economy seats we could find were into MEL/PER on Scoot). They are not really discounted (ex-SIN) especially for a LCC. Cost is about $1300 for one way 5 hour flight SIN-PER in economy (vs $150-$300 pre-COVID), but might appear discounted ex-ATH as the add-on is only a few hundred $$ more, not being capped.
We have flights booked for next month (ex-SIN) so will see how we go, I am concerned that McGowan wants to cut intake, in which case we're screwed. But, we didn't book on Scoot code (refused to), being a LCC, all their fares, no matter the price are non refundable and any changes can only be on the same route. But we discovered you could book full economy (fully flexible) using the SQ code on Scoot with SQ ticketing conditions (and same price as SQ metal
) if it is combined with another SQ sector, which is MEL-SIN. I suspect this trick wouldn't work for anything involving a connection.
