It's a bait and switch. They'll launch the bird with lots of room and
hype to match, then after it gets a reputation as comfortable plane to
fly, they'll quietly add seats until it's closer to th 550 number than
471.

*******s...

I don't think that is a given assumption, or it is not necessarily correct.

As has been stated here, Singapore Air sells luxury seats, and does very
nicely in the profit column doing it, and has been doing it for a while.
