Centennial Airport,
CO (KAPA) has consistently refused any attempt at an airline forming there, especially after Denver International Airport opened. There is a major NIMBY factor with the locals afraid of all the noise from B-737/A-320 series aircraft. The airport can't handle those types of aircraft now because the concrete is too thin, which weight restricts the types of planes that can land there.
There was a dispute between the City of Denver, United, and Frontier about gate allocations at
DEN.
UA grabbed some empty gates on the A concourse during their growth spurt in the late 1990s, and before
F9 became a serious competitor. When
UA cut back their flights,
F9 was greatly expanding. This left
F9 looking for spare gates because of all their flights, and
UA holding gates that weren't being utilized as much as they had been. The City of Denver was able to convince
UA to give some mainline gates to
F9 in exchange for more regional jet space.
