Looking at the numbers of the most directly affected bases PHL and CLT there are going to be a lot of displacements from the retired aircraft. Group 4 contractual requirements aside, I imagine if you were previously group 4 or even group 3 you would do what it takes to maintain your pay. If you are in your last 3 to 5 years the more you can save/earn the better. Even without decreased schedules due to the virus, getting rid of the 767 and 330 categories is going to create a cascade of training events. Why do I get the feeling that we'll all be shocked by the next bid? Unfortunately, not in a good way either.
