I understand why they can't announce the 6 weeks worth of cancelled flights at once (and therefore have up to 400,000 people phone them at the same time), and I understand that they can't do it too far in advance as they will be making desperate phone calls and this is probably an excellent and remunerative time to be a 737 pilot, ...
But the drip feed in this way, and flying people out without them knowing if they will be flying back, is the most damaging way to do this possible. Couldn't they find a happy medium by saying that they're cancelling the following flights for the next three days + the following flights to X destination for the next 6 weeks?
