I realize that you expect flights to operate as scheduled, and we make every effort to do so. At times, however, there are many unavoidable and unforeseen factors, beyond our influence, that can interfere with our flight operations resulting in delays and cancellations as you experienced. In this particular case, cancellation of the flight LX1370 was due to an unexpected flight safety shortcoming. We are, therefore, unable to comply with your request for EU compensation and sincerely hope you understand our position.
