I have a friend who works for Midwest Express as a ramp/gate agent. He told me a couple nights ago that the strike is being planned, but the airline will replace the striking f/as because, to quote him, "There are hundreds of people looking for f/a positions with our airline, so these people are expendable." My friend also said that the f/as are looking for a pay raise, among other things, and they will likely receive one, but not as much as they are asking for.
I'm flying YX on MKE-LAX next week, and am hoping things will go smoothly. I've been assured they will.
