When alpa was still on the property the east mec, refused to say "cactus" and the company went with two different call signs as , according to the company, a new call sign would be more than the east pilots could safely deal with. The new union has a resolution saying that usair is the only acceptable call sign, anything else is a "safety" issue. they also refused to wear the new uniform and that went to arbitration and they lost. And BTW the usair "folks" no longer have an issue with seniority has they have reordered the list so that 85% of west pilots will be junior to the most junior east pilot on date of merger. Yes that means that west captains will hit the street before junior east pilots, as a matter of fact pre merger america west pilots are being furloughed now while new hires (post merger) keep flying back east.
