You should look at the realistic numbers. For example, at Southwest, our plug captains are at 60% on master seniority list, and we operate a single type.
At legacies with multiple types, that number goes down significantly because a number of people would rather be widebody FO’s than reserve NB captains so that number gets distorted quite a bit. In the extreme case, Delta had first year Mad Dog captains. FedEx has first/second year 757 captains. 12-15 year upgrade at legacies or Southwest.... only by choice.
