OH MY GOD
Do you really not understand the dynamics of your industry?
Lesson #1. Airlines are not run on emotion. "A thorn in the side of Atlanta" ? Are you serious? Yes, thats the only reason we maintain our largest hub. To bother Delta.
Lesson # 2. Airlines are way more than pilots and flight attendants. Hubs are not dertermined by, oh, lets set up fort here and shift people through it. A Florida domicile? A domicile has nothing to do with where and how a company flies. Crew bases and hubs tend to be concurrent but don't have to be. Piedmont has a crew base in Salisbury MD, does that mean its a hub? Northwest has a domicile in Boston, United has one in Las Vegas, does that mean they are hubs? No.
Lesson # 3. The US airline industry is mature and well over its capacity. There are too many hubs as we speak, even after most of the airlines has either elimiated or dramatically reduced one. There's no "starting new hubs" at this late state in the game. The true effects of deregulation took a long time but the industry is in dramatic shift. Consolidation is coming and you will only see major airline hubs in major O&D cities. The network carriers in thier current condition can scarcely comptete in thier own fortress markets, much less randomly jump into new ones.
They can't just wake up and say La di da, isnt Florida nice. Lets set up a domicile in Tampa and randomly go into the LCC staurated Florida market, for 'points south'. While we're at it, move the planes out of Philadelphia to Pittburgh. Its a prettier airport and lots of employees live there. It'll be great!
Please explain "You never put a domicile in the center of your route structure". I am really looking forward to hearing what on earth that means. Please enlighten us.
