Enter your flight number and get the delay probability based on real data.
Our predictions are based on real flight data from AviationStack, including recent departure and arrival records for each route. Accuracy depends on the amount of historical data available — flights with more history produce more reliable estimates. For flights with limited data, we show a baseline probability and clearly indicate that data is limited.
We cover virtually all commercial airlines worldwide, including major carriers like Delta, United, Lufthansa, British Airways, Ryanair, EasyJet, and hundreds more. If an airline has an IATA code and operates scheduled flights, it should be searchable. Regional and charter flights may have limited coverage.
