It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 9 years ago.

Kayak API: The search API is an HTTP interface that lets you, the programmer, integrate kayak.com searches and results into your web site, desktop application, or mobile phone application. Below is the mashup Kayak Buzz that answers the question: “Where can I go for under a certain amount of money?” It displays airfares under a user defined amount of money on a Google map. http://www.programmableweb.com/api/kayak

TourCMS http://www.tourcms.com/support/api/mp/examples.php, which has lots of users examples about how to use the api.

FlightAware API: Using the FlightXML API, programs can query the FlightAware live flight information and historical datasets. Queries for in-flight aircraft return a set of matching aircraft based on a combination of location, flight or tail number, origin and/or destination airport, aircraft type, and/or a low-to-high range of altitude and/or ground speed, among others. For each matching aircraft, data returned includes the flight or tail number, the aircraft type, origin and destination, time the last position was received, and the longitude, latitude, groundspeed, and altitude of that position. Matching flights’ flight tracks can be requested as well. For airports, FlightXML queries can return a list of scheduled flights, flights that have departed, flights that are enroute to the airport, and flights that have arrived at the airport. http://www.programmableweb.com/api/flightaware
