That is just a poor risk assessment. On par with parking your investment cash in a money market account because "the recession is right around the corner". Every one has a risk tolerance but staying at a regional because you might get furloughed is about the same as building a castle in the woods for a zombie apocalypse. There will always be regionals hiring with fast upgrade times that will be able to replace your current income and the reward for leaving is quantifiable. Even the worst of the worst times in the industry presented an experienced pilot with employment pretty quickly. If someone gave me that excuse I would understand that their decision making is flawed or they were delusional.
