United is increasing mainline service in the Billings - Denver market from 2 to 3 daily 737 flights beginning February 14, 2007. United is definately increasing their presence in Montana at BIL (additional mainline to DEN), BZN (Daily ORD non-stop on SkyWest) and MSO (additional United Express flight to DEN). Status quo at GTF. Wonder how long until they start service to FCA?
