In Canada it used to be like this, but they passed legislation that advertised prices must include all the fees etc. For some time this worked well and ticket prices didn't suddenly double on the last booking screen.

Then came the rise of the discount airlines, where it tells you your ticket is $58, and it is, but if you want luggage you now enter the world of tiered add ons. $58 only covers you and a 10kg carry on. You want a piece of luggage? Additional money only added in at the add tier screen, because the base ticket price is 'correct' and there's no standard for how many pieces of luggage the advertised ticket should include, so they advertise the price with 0.

if they could advertise a 'standing room only' and force you to upgrade to a seat I bet they would. Maybe you need the first luggage tier for washroom access? The nickel and dime sort of approach is exactly what made the dishonest prices the first time around detestable.
