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
A 20% chance of missing a connection at a hub with a flight every hour is an annoyance. A 5% chance of missing the last flight of the day is a night in an airport hotel. Those are different products sold at the same price, and nothing at booking time tells them apart. GateCast is an attempt to fix that.
What it is not
GateCast doesn't sell tickets. It isn't affiliated with any airline or airport, and no airline pays for a grade. Prices shown come from a recent price check, and the link to check prices goes to a third-party booking site.
Where the numbers come from
Flight histories are US Department of Transportation records: 3.6 million flights across 98 airports, October 2025 to July 2026. Terminal layouts and airline terminal assignments come from the airports' and airlines' own published information. How grades work has the detail.
Who's behind it
GateCast was started by a working airline pilot. The "From the flight deck" notes in the connection guides are first-hand.
