What could be the main reasons for a short-haul flight to be delayed over an hour in-flight?
Recent Lufthansa LH 2227 CDG-MUC flight took off only half an hour after scheduled time, but landed at destination delayed nearly an hour and a half.
Meaning (if I am reading these stats correctly) that this particular flight spend an hour extra in the air over scheduled time. I begin to question if there is enough fuel for the plane to stay that long extra?
I flew the very same flight few days ago and that flight also took of half an hours after schedule and landed fifteen minutes after schedule. Meaning that a plane manage to "work out" half of its delay en route. This particular, pictured flight not only didn't work out its initial delay, but also added another hour to it while being in air.
I was always told (and saw that in my small commercial flying experience) that
- short- or middle-haul flights delayed 15-30 minutes on take-off,
- long-haul flight delayed 60-90 minutes on take-off,
are nearly always able to land on-time, effectively "working out" their initial delay during flight, by flying faster etc. What happened or could happen here?
