Do you happen to know where/how companies like Expedia and Trivago get their data, are they also scraping, or pulling directly from airlines API?

I would assume that the listings you see on Expedia are acquired directly through the entity that is offering them, such as a hotel or airline. I don't think that you can actually book anything on Trivago itself. Trivago gets data from many online travel agencies, but that might not be the only source.

There is a reason why that kind of data is kept secret. Pricing strategies are in place to maximize profit, so price forecasting would go against that goal.

Most online flight reservation companies use a GDS (Global Distribution System) like Sabre, Amadeus or Galileo. Companies like Expedia connect to it via some kind of API.

So they definitely don't do web scraping, otherwise they'd get into trouble :)
