I know this question has been asked before, but none of the previous responses seem to work/are relevant. Can anyone recommend (preferably free, or cost-effective) travel APIs, to grab flight, hotel, etc info? Thanks!
We just used the Expedia Affiliate Network from http://www.Mashery.com or http://www.ean.com to build a simple jQuery Mobile app that did hotel search - you can even earn money from it with affiliate ids. We didn't try to build anything with flight or rental car though.
