*** Delta and American Airlines flight loads are back as of 12/1/2015! *** NonRev is a term used by airlines to refer to non-revenue passengers, that is, passengers flying for free. This includes airline employees and their families, as well as buddy pass travelers and so on. Generally NonRevs travel standby and are given seats only after paid passengers are accounted for. NonRev app helps you plan your NonRev adventures by allowing you to search for flights and see an estimate of how good your chances are of getting a seat on any given flight.* NonRev app is subscription-based, however, even without a subscription you can search for flights between LAX, JFK, ATL, ORD, and LHR. *Due to technical factors, currently no NonRev status is available for Southwest Airlines.
