What GateCast does
Every flight search site rates flights. GateCast rates the connection: the chance that your first flight lands, you get across the airport, and your second flight is still there. Each itinerary gets a grade from A to F, and each grade comes with the working behind it.
Why it exists
The consequence can be as different as an easy rebooking or a night in an airport hotel, and nothing at booking time tells you which you're buying. GateCast is an attempt to fix that.
We also grade connections at five Brazilian hubs, from ANAC records.
Limits
GateCast doesn't sell tickets. On US trips, each card shows a typical fare from the US DOT fare survey: a guide price from past tickets; the price you pay is set when you book. GateCast is not owned by, paid by or endorsed by any airline or airport. Booking buttons go to Kiwi.com, Expedia or southwest.com; see Affiliate disclosure for which ones earn us a commission.
Where the numbers come from
For US trips, flight histories are US Department of Transportation records: twelve months, August 2025 to July 2026, more than 4.0 million scheduled flights between 99 US airports, counting each flight number that ran on at least 40 days. For trips in Brazil, they are the public records of scheduled flights in Brazil kept by Brazil's National Civil Aviation Agency, ANAC (Voo Regular Ativo, VRA), September 2025 – August 2026. Terminal layouts and airline terminal assignments come from the airports' and airlines' own published information.
Who's behind it
GateCast is made by Wingmark Analytics: wingmarkanalytics.com.
GateCast was founded by a working airline pilot; grades come from a fixed method applied to public flight records.
