Mountain Air Express (MAX) was a short-lived commuter airline in the United States founded in 1996.

The air carrier was established by Western Pacific Airlines in order to provide passenger feed.

Great Lakes Aviation and Air Wisconsin were then selected as the new United Express carriers replacing Mesa.

The purchase of MAX gave Air Wisconsin the aircraft and crews it needed for its newly expanded code sharing agreement with United Airlines.

The following destination information is taken from Western Pacific Airlines system timetables dated June 29, 1997 and November 16, 1997, as they contained Mountain Air Express flight schedules as well.
