Ahhh I can just imagine getting a sudden equipment swap to a non-refurbed Silkair plane doing some of the longer 'regional' routes. Unlikely to happen but fun times if it does.
I'm surprised that they would suddenly dilute the SQ brand business class from being all flat-bed when the A330s are fully replaced, back to a mix of flat-bed and lie-flat given the marketing and branding they did for the new regional product.
