you wouldn't upgrade anyway until you senority can hold it regardless of hours hired at. So in other words since eagle upgrade time is longer everyone has above the required upgrade flight time by the time their respective senority can hold it. at an airline with short upgrade times, what your asking is true, it possible for someones senority to be able to hold captain before they have the hours in which case the company would go down the list until someone has enough hours. make sense, again this is not an issue at eagle and probably won't be at many places real soon.

and also in the second situation, when the person who got skipped over for lack of hours upgrades, you will be back below them
