I'd also like more information about the flight: quality, seat comfort, meal included (or pay for on the flight), meal rating, flight entertainment (in seat, group, none), cleanliness, etc.

I'd be willing to pay a little more, if the flight wasn't like being in a metal torture container or the cleanliness levels were so poor that I get to my destination with an immediate illness. But right now I can only see that some flights are more expensive than others and no idea why. And I have to go off of my average experience with an airline to guess if the flight will be pleasant or miserable (except for United domestic, that's always miserable).
