This past week, Southwest responded to the most recent setback for the Boeing 737 Max. Southwest is now extending the cancellations through October 1. This will impact approximately 150 flights per day, but by canceling now it will help with last-minute cancelations this fall. Boeing has been working hard to fix the problems with the 737, but the FAA has recently said they are not ready and Southwest responded to that inquiry. Other airlines most likely will cancel through Oct 1 as well.
