Now do the same with airline companies. WizzAir charges the crap out of you for everything they can. Do not fly with WizzAir!
A recent WizzAir flight was advertised (when I searched for the route on their website) for €21. I rejected all optional extras, and that was the total price I paid.
No checked luggage, probably only a small cabin bag that fitted under the seat in front, no priority boarding, no seat selection.
It's a budget service, but the advertised prices aren't deceptive.
Trust me, you got lucky, they "randomly" selected passengers with those kind of bags for inspection due to measures, 1mm above? charged! Emphasis on randomly, because the pattern was simple: foreigners? charged, locals? go on. We've saw a poor guy squeeze the hell out of his backpack to no avail, it fitted the measuring box, still, charged because "you had to squeeze it"; guess what, plenty of room under the seat, the guy could put two of them. On me? bag had wheels, foreigner, automatically selected for inspection, took the wheels away, still charged because "it had wheels first". I've flew a dozen companies, not even Ryanair, the low of the lowest treats passengers like this.
A significant difference here is that the airline fees are ostensibly optional. You could, in theory, fly Spirit with nothing except the clothes on your back and they wouldn't charge you extra. But with event ticket sales and the like, there is often no possible way to avoid the fees. That means there's a much stronger argument for requiring that the fees be rolled into the price.
Or they do something silly where there is an "Online Convenience Fee" when you buy online, but if you try to buy it at the box office, there's a different "Box Office Ticketing Fee." The event promoter should pay the cost of their ticketing service provider(s) out of the money they make, not have the purchaser pay it separately.
That's not in the US so unaffected.
