I think that's great. Anything that can help this company expand is good. However I question the motives. I have a hunch the reason they are sucking up all available space is because they don't want another airline to swoop in and make DFW a mini hub.
That being said it makes me excited they are wrapping this up. They are, actually, thinking long term on this one. Seriously, Kudos to Doug and Isom. I was wondering when they would announce it.
