Call me old (UA) school but I still prefer Purser......Anything with the word "manager" in it makes me think of someone sitting behind a desk, i.e, Station Manager.
Somehow a lot of confusing CO lingo took hold at the merger. Took us weeks to figure out what "redisplay the bags" meant. This was used in conjunction with bags being returned to the baggage claim (ie., a cancelled flights and all bags offloaded and returned to the baggage claim area for passengers to retrieve). Redisplay ?? the bags ??.....sounds like a new window display at Macys.

At United we would be told the bags were being "dumped" back to baggage claim.....simple. All ramp and customer service agents knew what it meant by that one word. Yes, kind of a "crude" term but it was an internal term and passengers were simply told to retrieve their bags at baggage claim.

Back to the subject at hand.....I find CO's terminology confusing and why are there two different terms for this person (on international flights they are ...managers and on domestic flights they are ....coordinators)? I know passengers probably don't give it a second thought (or even remember the terms) but purser sounds familiar to most people and can be incorporated as "Your purser or lead FA on our flight today is ....." if they even need a definition in this 21st century.
