I'm not saying that you can't have unbundled pricing, or go with an ultra-economy carrier if that product suits you best. I'm saying that listing ultra-economy in the same search results as (now so-called) "premium" economy is a race to the bottom. We can stop this race if we just define a standard bundle and force competition on the basis of the bundle price. If they could charge you extra for the privilege of taking the clothes on your back, they would. I'm surprised they aren't already charging to use seat-back entertainment (or "limited ads" seatback entertainment) or the reading lamp.
