Interesting -- I could not get YX to come for MSP-MKE just now, and Midwest is not in Expedia's dropdown list of airlines.

They cancelled a lot of routes & refused to rebook countless customer itineraries in the past few months. They did rebook two of mine (originally booked through Travelocity) on NW but it's taken many hours on the phone. Once rebooked, they seem to hold back on paying NW so the itins can be ticketed & confirmed.

Maybe the agencies are dropping YX? If that's happening, the end is nigh.
