Haha, I laughed out loud at this. It wouldn't cost them much more to have some "premium"-looking BPs, especially out of MEL which I presume is a large market for SQ (I mean they have 5 flights a day MEL-SIN so clearly MEL matters to SQ).The check-in staff joked that this is the new Non-Discriminative and All-Inclusive Initiative by Australian Airports to make F / J Pax feel like part of crowd.
The reason they cheap out on BPs is very bad (especially if you're connecting to another flight so that flight's BPs also get the all-white treatment, unless you take the time and effort and energy, as CE said above, to get the onwards flight BP reprinted at SIN with the correct "livery").
Call me OCD/paranoid/entitled etc but the point (pardon the pun) still stands - when shelling out exorbitant amounts of money/points you want every part of the experience to be the best it can be: after all, some (myself included) like to keep BPs as a memento. For a lot of people, flying in Suites is something they'd only get to do once in their lives, maybe twice if they're lucky, simply due to the fact that they just don't have the disposable cash to do so and/or don't have the mammoth spend (read: points earn) that is attached to running a business.
My first ever SQ Suites flight was the one that kicked off the honeymoon with the wife, and having that all-white BP did cheapen the experience. Whilst I still have kept the BP, looking back on it, I'm sure it won't get the same "wow" factor.
FWP, I know.
