This reminds me of a recent call I had. We were in Dubrovnik. Our flight back to London, having failed to land because of wind, diverted to Bari and was clearly, like the previous attempted arrival, going to be sent back to London. We had been sent back through immigration, and there was a very long queue for buses. I called the gold line to see about some re-booking options. We were told, with what I imagine was an absolutely straight face, that the BA Flight Tracker, which at that moment still showed the flight as departing in about 15 minutes from the time of the call, and when the plane was (I forget) either over the Adriatic in the direction of Bari or on its way back to London, was absolutely correct, as the BA Operations Department 'updated it in real time'. I gave up.
