I had seen this in Great Lakes schedule... but it seems that Great Lakes airlines had scheduled service at PHX to Page, AZ and onward to Denver via a few more points in Western Colorado.
Now this seems odd to me. First of all these are not United Express flights. Secondly Great Lakes has no other presence at Sky Harbor other than the Page flight.
So was this flight subsidized or just an oddball that may have been successful.
