Web Services?

[eluser]Iverson[/eluser]
THIS post is why CI has the best PHP forum on the internet. Hands down! :coolsmile: I'm about to start looking at the REST controller... Thanks guys! Maybe I'm jumping the gun here by asking this before I read, but how does this relate to car rental websites, airfare sites, etc.? Are these people paying to access the airlines' web services or is there somewhere where you can get an api or interface?
