Before ya'll get carried away with the DEN base closing notion....know that DEN has more mainline daily depts than LAX or IAD, and 5x as many as CLE. Denver has deathstar alliance 747 service to FRA and mainline 787 service to NRT. In 2012, UAL and the city of Denver worked out a deal to forgive 100M in debt (not a typo) if certain growth parameters are met. SWA threatened a lawsuit to stop that deal. DEN ain't going nowhere, SEA on the other hand....

JMHO,
