Concourse C/D is being replaced economically at Dulles. Costs have been a problem for a long time. In 2013, Jeff Smisek, then-United CEO, stated that Concourse C/D was being replaced economically at Dulles.
We have to find a way to make it work and not ruin the economics of the hub. They built a beautiful facility here in Pittsburgh, but there is no hub anymore. Kirby agreed with Smiseks sentiment and said that we have to do it intelligently.
