And how airfare comparison sites are required by law to show full prices, not before airport fees etc. the way they did way back when?
It's time for the same kind of legislation to be applied to car rental companies, and enforced on reservation sites so their policies apply worldwide (e.g. when an American books a car to rent from Hertz in Spain, they can't resort to saying it's a foreign subsidiary the law doesn't cover). I'd say they're now the #1 source of sneaky fees and hidden upsells, even worse than banks, cell service providers, and internet providers at this point.
Surprise fees at time of booking should be illegal (e.g. "driving out of country"), and "extra processing" fees (e.g. for a toll with no choice) legislated to a reasonable level (e.g. $5 instead of $50) -- the same way credit card late fees are currently set by law. And toll transponders included in the base price in any country that has any roads where paying in cash is unavailable.
Where's the movement for this? Why aren't we all writing our representatives about this?
