I just don't think that "seeing what is included in a airline ticket" is all that complicated, or that it is simpler somehow than deciding on, administrating, and enforcing a "standard bundle" on all these different airlines. And there's nothing to say that the standard bundle will necessarily meet that many people's preferences. I mean, people distinguish between different services and goods all the time depending on how much they value them - I don't think they suddenly lose this ability when comparing flights.

The airlines are incentivised to make it complicated, and just dealing with n different website layouts is challenging enough. Compare to e.g. food labelling, where we require mass in specific units and nutritional information in a specific format, or cars, which are obliged to include mpg and safety information from particular standardised tests in their advertising.

It doesn't have to - the point is just to have a point of comparison to be able to compare equivalent offerings from Airline A and Airline B, even if you end up getting a very different bundle from the standard one.

Well, maybe you could have a price-compare thing, and that seems vaguely reasonable, but what everybody seems to be talking about and demanding is that there be a required bundling of certain services. A mere labelling is quite different.
