BA247 GRU = not cancelled, delayed overnight due to technical issues, arrived something like 20 hours late.
BA482 BCN = ARPN - ATC congestion
BA520 FLR = not sure, but seems APRN due to ATC overload
BA488 BCN = ARPN - ATC congestion
BA992 BER = ARPN - Collins
BA982 BER = ARPN - Collins
BA392 BRU = ARPN - Collins

Poor timekeeping all day long today, thanks to the knock-on effects of Collins throughout the European network.

Monday 22 September 2025
BA392 BRU = APRN - Collins - cancelled on Sunday
BA396 BRU = APRN - Collins - cancelled on Sunday
BA398 BRU = OPEN - this is an awkward one, they were intending to fly this service on G-EUYX but it got stuck in BRU on a previous excursion and was thus too late back to LHR. Open to challenge but I suspect not successfully, it probably counts as extraordinary. But people should claim anyway.
BA822 CPH = APRN - drones closed the airport.
BA31 HKG = WEAN - see below

Busy day, 674 LHR departures despite the cancellations, timekeeping in the 60-70% area. BA departures were 340 in all.
