It’s expensive to get access to a GDS API and, from what I’ve heard, the data they provide is quite difficult to work with. There’s a reason Google bought ITA for $700m, right? If this project ever grows, it could make sense to pull from a GDS.
Well, it’s expensive to provide live answers for flight search queries across hundreds of airlines and thousands of airports... Some of the old booking interfaces are ugly, but for simple searching most of them provide relatively sane REST/JSON
I don’t understand your attitude, steal it until you make it?
Meanwhile on the topic of attitudes, referring to a startup as 'pond scum' simply because they scrape an extremely expensive data set, especially regarding an industry with a long and controversial history of strategies designed to avoid price transparency.. hmm.
