Thanks Mill for posting. As far as vision
demolition of all concourses at Terminal 1 to be replaced with a single long concourse similar to Austin, Detroit, or the future Salt Lake City airport
I agree that this vision for Terminal 1 is way out there as matguy70 noted with all the rebuild of existing gates. However, you could almost make the current concourse A & C linear by adding gates between them in a modified version (mix of new and existing) & converting/rebuilding B into a new security access/customs & immigration area. re open gates at the end of concourse C when you take out some of the current gates for constructions
a westward expansion of the main Terminal 2 building and an eastward extension of Concourse E
Isn't this essentially happening in respects to utilizing the current terminal/concourse E?
an eastward expansion of the Terminal 2 parking garage
a new building between the two terminals where Concourse D now stands, possibly a hotel or parking garage.
I think in short term this could very much be considered even after you remodel the four Concourse D gates. Lambert still has way too many under utilized gates and even being a Southwest focus city it will not bring back demand for all those gates. Airport should find ways to maximize parking near airport as it will only improve revenues as well as give Lambert the hotel option.
