JSONP call showing “Uncaught SyntaxError: Unexpected token : “

Question 1

Working fiddle:

http://jsfiddle.net/repjt/

$.ajax({
    url: 'https://api.flightstats.com/flex/schedules/rest/v1/jsonp/flight/AA/100/departing/2013/10/4?appId=19d57e69&appKey=e0ea60854c1205af43fd7b1203005d59',
    dataType: 'JSONP',
    jsonpCallback: 'callback',
    type: 'GET',
    success: function (data) {
        console.log(data);
    }
});

I had to manually set the callback to callback, since that’s all the remote service seems to support. I also changed the url to specify that I wanted jsonp.

Question 2

You’re trying to access a JSON, not JSONP.

Notice the difference between your source:

https://api.flightstats.com/flex/schedules/rest/v1/json/flight/AA/100/departing/2013/10/4?appId=19d57e69&appKey=e0ea60854c1205af43fd7b1203005d59&callback=?

And actual JSONP (a wrapping function):

Search for JSON + CORS/Cross-domain policy and you will find hundreds of SO threads on this very topic.
