Are you saying they can't be trained? Seems that is an easily solved problem just requiring some time. But I would think, using the scenario that UA acquires Mesa in a merger, the Mesa flight attendants become UA employees, as do the Mesa pilots, so there is no violation of the agreement, no new training required (while other than Indoc,), however, there is a problem of seniority that the Mesa employees are not going to like because they will be new hires at the bottom. That is something the unions would have to iron out.
