Eurocontrol logs weather delay at Belfast Aldergrove on specific days; if your day is not one of them, the weather defence has nothing behind it. If it is, the airline still has to connect it to your flight.

Enter the flight number and date in the checker above. It pulls the recorded arrival time, works out the delay against the schedule, and shows what Eurocontrol and the airport weather logged for Belfast Aldergrove that day.
