Well, that seems obvious ? Of course they are? If you've booked a flight at a certain date, it's obviously because you need transportation at that date. If you cannot be transported at the right time, the transportation is in many cases no longer needed. For instance, if I miss a conference, my need for the transportation goes to zero, and so, I should be reimbursed _AT_LEAST_ for the transportation, but I'd argue, also for the conference if that payment has already been made.
