It is interesting to hear of all the talk of expansion at DIA - the airport that was supposed to be big enough for a long time to come.
When DIA was being planned, Continental still had a hub at Stapleton, and the design of DIA was for that to continue in Concourse A. By the time DIA was finished, Continental had pulled out of Denver. Going through DIA when it first opened, Concourse A was like a ghost town when compared to the activity at B. It is nice to see that Frontier has filled that space.
I read another post that it would make more sense to shift Continental over to C and use those gates. I would guess with the right incentive, Continental could be persuaded to move.
I have a hard time
UA has got its nose in city hall to the extent suggested. They are too busy with surviving. If anything,
UA's response to Frontier will be to structure their "Starfish" routes to compete with Frontier. Frontier needs to consider that every leisure traveler does not want to have to change planes in Denver if they can get a non-stop. Its time for them to think of another hub or focus city.
