This site allows users to search for hidden city ticketing. There are some good instruction pages out there. I've never personally used it since I live in Canada and spoke and hub isn't really a thing up here.
All sorts of fun games on ITA. Another good one is to set very long connection times, to get a 23 hour stopover in an interesting city for free.
It's not always a scam to do this; Cathay Pacific seems to give you a discount if you spend a day in Hong Kong.
Right, that is a definite feature of some fares. They allow a free stopover at their hub if you want. Given that, almost all fares allow a 23 hour connection without it having to be programmed into the fare.
And I didn't mean it was a scam, more like a cool hack.
This is an awesome platform, if only you could purchase through this!
That's where the money comes from -- and ITA's mission was to be a backend for other people, who would deal with the expensive customer service side themselves.
Presumably as a Google service, customer service isn't a priority anymore.
Their plan is probably to enable it at some point.
