But they don’t actually sell business class as such anymore ? They brand as “Plus” , a bit like Scoot (who sell Scoot Plus vs Jetstar who gave Jetstar Business).
Flew them recently in economy as star gold. Priority boarding worked well. Secured an exit row seat free of charge and actually had an empty seat beside me . Nothing special they are effectively a LCC. At least they had complementary tea and coffee, some airlines (looking at you Brussels Airlines - think are worse, although they do come with proper Eurobusiness).
