BA254 from BGI on 18 June into LHR on 19 June was delayed by almost three hours, landing at 08:45, according to FlightRadar24, the incoming flight having been delayed out of LHR, where the plane had sat for a couple of days since previous use. We then sat on the tarmac for a while waiting for steps to arrive, the captain saying we were caught between BA and the airport, both of whom were short-staffed. However, we were parked at the wrong terminal, T5, when the flight was due into T3. The flight was meant to arrive at 06:30, doors were opened at 09:22, the first bus departed at 09:25 and it arrived at T3 at 09:32 (I took a photo from inside the bus to prove the time), at which point the bus doors were opened, two minutes over three hours. Is there merit in claiming that, since the aeroplane had arrived at the wrong terminal, plane doors open isn't the right metric, but bus doors is, as that's analogous to plane doors opening onto a jet bridge at the correct terminal?
