Well it was several weeks ago when I read it. I see your point and agree LCCs focus on O&D traffic, but except for maybe Virgin America, they all have hubs to some extent, even if by happenstance in some cases. In fact, if you think about it, Southwest, which many anlaysts consider hubless (I was glad to see the white paper not take this approach), has more hubs than any airline, if you define hub as a connecting center. Take LAX-FLL for example. In addtion to their direct one and two stop flights, you have the choice of six connecting hubs on this one route: LAS, DEN, STL, BNA, HOU, and MDW. I was actually surprised I didn't see PHX in there too, at least at one time one of their biggest "hubs". Southwest has already become the largest domestic carrier in terms of passengers flown and they always grow and oneday may have a more sophistaced hub network in addition to all their point to point flying now. The traditional carriers did not start out with hubs either, they evolved over time, especially after deregulation in 1978, and right now we are seeing other fundamental changes which could reshape the industry. While hubs are expensive, they are very efficient, and LCCs with lower pay scales (like I said before with maybe the exception of WN) are eventually going to run out of opportunities with enough demand for point to point flying. If we have only 3 network airlines left, which may cut approximately 10-15% of their domestic capacity as a result of mergers, even while enjoying 80% plus load factors, don't be surprised to see LCCs look for other domestic opportunites outside of their box. Jetlbue has more than one type aircraft from two different planemakers and I am not a pilot but aren't we seeing more commonalities in cockpits now that jets are becoming more sophisticated, even accross different a/c types? Boeing could always develop yet another smaller and larger derivative of the 737 to apease WN if they flat out refuse any other type of aircraft, althought I think WN is made it clear nothing is off the table. I also wouldn't be surprised to see international carriers approach LCCs with alliance opportunities similiar to what we have already seen with JetBlue. I am sure many airlines abroad would love to team up with Southwest.
