Earlier quoted context omitted.
> changing the language and country of the website changes ticket prices That's a feature. Nothing will cost the same if you buy it in Nairobi or in London, because price is a function of demand.
So we need an API to search all the languages and countries, pay in the appropriate currency, abstract this "feature" away along with the language barrier, and give me the lowest price. I hope Google will do that. :)
There are industries where profits are huge and disruption is badly needed. Airlines are not one of them, afaik; ever since low-cost became a thing, they've been under constant economic pressure and usually operate on razor-thin margins, at least in Europe. Mid-size companies have all but disappeared, even giants like British Airways and KLM have been permanently de-structured.
Flying is an expensive and risky business, piling up the pressure is likely to generate even more safety issues than we already have today. If you're all about price, just fly with RyanAir and be sure that nobody can ask you for less money than they do.
