On Wed Oct 4th, I got to Bologna Airport (BLQ) very early for my flight, so I ended up sitting at Gate 12 for a couple of hours (from about 8am to 10am), with a nice view over the runway. I probably saw 10 or more arrivals in that time, and a similar number of departures.
Now here's the curious thing: every single one used runway 12 ... except one !
For some reason the BA aircraft which left while I was sat there (perhaps BA543 ?) took off in the opposite direction using runway 30. At the time I thought, "oh must be runway changeover time like at Heathrow but then every subsequent aircraft started using runway 12 again.
Any thoughts on why a single movement should be switched like that ? Just curious really
