The media solution
Dragon Air were proactive about getting their story into the media, and letting the public know why so many flights were being grounded.
CX have done a great job of keeping the CX crew shortages under wraps. Sooner or later it will get out. Right now they are relying so much on good will to crew the flights, robbing Peter (sorry Pete) to pay Paul on many flights every day.
Obviously they will need to extend the retirement age, and move to 3 man ULH to keep crewing aircraft....don't be surprised.
Much of the crew shortage here is a result of crew leaving before normal retirement age to go to other airlines, and the most common reason they leave is because of the way they have been treated over the years.
This says alot about the type of employers they are.
