Here we go again... Imagine if Atlas somehow merged with Alaska Airlines. Would the Alaska pilots automatically drop to the bottom of the combined list because their 737s are smaller than Atlas 747s? That is unrealistic thinking. That sounds like USAirways East thinking. Remember who is buying whom...
I don't see your point here. If what you're trying to say, is that Alaska pilots were to be stapled, I would assume they still get longevity. Therefore other than bidding a lower number, they would be still making the same money. (except the most junior FOs) It all comes down to fair pay for equipment flown. And if that is the case, Alaska pilots get paid more with relationship to aircraft size.....So your argument is moot!
