I also like the seasoned front-of-the-bus flyers that post their apples to oranges comparisons.
Airlines make the bulk of their profits on those who 'turn-left' at the door when boarding. Since they have maxed-out their profits with the limited variations allowed in Coach, ie. economy, economy plus, economy lite, 3-4-3, 3-5-3 seating and other nuances beyond a few more inches of legroom, 'premium' meals, paying for checked baggage and the like, the focus is on the business (or better-off personal) traveler.
At the front of the airplane, there are increasingly more variations and price banding options, but that depends on the fleet size, destinations served, length of non-stop sectors, etc.. Not all airlines can afford to offer the individual suites and cabins that SQ pioneered and Qatar have tweaked. Thai learned that they cannot compete, as have most who bought less than half-a-dozen A380's, with the higher-end, longer-haul airlines. Good luck to them in staying flexible enough to work profitably and safely in an industry where the dynamics are rapidly changing. To me, it's a bus that flies and airports are bus stations.
Disclaimer: I have never worked, or pretended to work, in the airline or travel business. Just a tired old frequent flier who misses the Constellation and the stopovers in Constantinople, Delhi and Rangoon.
