I wouldn't be so sure of that...this is a quote from Crandall on a local DFW radio station the last Friday after the announcement.
Former American CEO Robert Crandall spoke exclusively with KRLD NewsRadio 1080 and said that while US Airways may have made deals with the unions at American, they haven’t done that with their own unions.
“The unions at US Air itself have not been able to agree with one another, and with the management at US Air, about what the labor contracts at US Air should say. I must say that that’s a vastly complicating aspect of trying to put the two companies together,” Crandall said.
However, Crandall said he believes the merger is a good idea in the long run, because the combined US Air/AA company would be able to compete with the large-scale business services provided by both United and Delta Airlines.
“It may very well be that putting these two together, in one way or another, makes some sense. Whether this is the right way to do it, I think at this juncture, is open to discussion.”
