What is the point for this if only those who are working for Airbus or Lufthansa are allowed to go on these flights, the usual "chosen few".
They should have had drawings among the airlines highest level frequent flyers in order to decide who would go on these route proving flights. They are the ones with the most flying experience and therefore more capable of testing an aircraft than occasional guests chosen by Airbus and in this case LH.
It will be a lot more interesting to get reports from the flyers on the first Singapore Airlines flights from those who have paid for their tickets.
