FlightCaster predicts flight delays, often hours before the airlines. From the developer page: "The FlightCaster API is primarily used for retrieving information about the likelihood that a flight will be on time. Although other information is available as well, such as general airport information, general airline information, general weather station data, METARs, and TAFs."
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
