I think many still don’t get the magnitude of the crisis commercial flying is facing. At the point we are at right now, nothing I say again nothing any airline could come come up with in terms of money saving measures would make it survive.
The only difference will be made by governments aid and heavy credit lines.
The reason is simply that the airlines are not built or meant to sustain something like this, never mind the 300+ aircraft airlines who have always only made money by expanding. The margins are simply too thin, you don’t need to be a phd in economy to see that another 6 months of this are not sustainable for most.
