After a dreadful weekend of cancelled flights and cancelled Christmas plans for passengers, Southwest cancelled 70% of its flights on Monday. They threw in the towel – which would hopefully have given them time to put planes and people back in position and get employees legally required rest. Major disruptions take days to recover from because aircraft and people are left in cities that aren’t where they need to be.
However they have already cancelled 62% of Tuesday’s schedule, and 62% of Wednesday’s schedule. They may not operate more than a third of their flights through end of the year.
