Read full description

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.

Your all-in-one standby copilot. Kova is an engine that predicts if you'll clear. Every standby flight comes back open, tight, or full, with the number of open seats it expects and what's moving that read. Find the open flight Search any route or flight number. Best odds on top, nonstop and connecting. Filter by airline, sort by time, and save a flight in one tap. What's moving your read Kova weighs live conditions and how the route usually runs: your boarding priority, how many non-revs are listed ahead of you, the aircraft and its cabins, weather upstream, cancellations nearby, and how it's booked. It's the answer you used to wait on the crowd for. Watched the moment you save it Delays, cancellations, aircraft swaps, seats opening up or filling in. Kova tells you the second your read changes, so you're never surprised at the airport. A way home when you don't clear Get Me Home uses your location to find nearby airports and the best flights toward your home airports, today and tomorrow. Drive-plus-fly options, not just the next flight. See where you can get on Explore puts every destination you can reach from your home airport on a map, ranked by your chances of getting there and back. Your trips, on autopilot Save a whole itinerary with a backup for each leg, see your chances across the trip, and share the plan with whoever's flying with you. Every leg watched, with a backup ready. When one looks shaky, Autopilot shows you the way around it. Accurate loads, straight from other non-revs Ask about any flight and a non-rev at the gate sends back the real open seats, cabin by cabin. Answering someone else's request is always free. And more Commuter Mode watches the trip that gets you to base and alerts you early when it's at risk. Live Activities put your open seats and boarding countdown on the Lock Screen and in the Dynamic Island, and a Home Screen widget keeps your next flight one glance away. Some features require Kova Pro. Built for non-revs Kova is for airline employees, their parents, partners and dependents, and anyone flying on a buddy pass. Kova is an independent app. It is not affiliated with, endorsed by or operated by any airline, and it never connects to airline employee systems. Every read is an estimate.
