That's the funny thing - unlike some, I don't need the satisfaction of hearing others validate my opinions, right or wrong, and somehow concluding that my acting arrogant and uninformed constitues some sick form of "winning" something. Different strokes.
As to this issue, AA thankfully today provided us all with the specifics that validate that yes, indeed, the new regional capacity is, in fact, largely replacing small jet flying. AA's monthly investor update included the fleet plan going forward which showed, clearly, that Eagle's fleet count net-net YOY is essentially flat, with 44-seat EMB140s being replaced pretty much 1-for-1 with large RJs - at an increasingly rapid pace. Delta may be reducing its overall RJ footprint more right now, but as I already said, I doubt AA is too far behind, since AA has a very healthy order book of both large RJs and new mainline aircraft on the horizon.
As for the rest of your B.S., no, actually AA is plenty diversified with regional feed - with a total today of 10 operators from 6 parent companies (Delta: 7, from 4 parent companies), so that argument's out the door. And that assumes, of course, that one considers regional feed diversification to necessarily be a good thing, which I personally don't. Long-term, strategically, I think it's a bad thing and I suspect all three carriers - AA, Delta and United - are very shortly going to be utilizing a much shorter list of operators, and for good reason. But that's a different discussion. As to the fleet count, I also find it funny that now somehow AA not reducing their fleet as much in bankruptcy as Delta is a bad thing, when relatively recently we were hearing how AA was in such dire straights that it was going to have to shrink so dramatically. Yet more revisionist history. In reality, the fact that AA didn't shrink as much in bankruptcy as Delta was a reflection of the fact that it didn't need to - it entered bankruptcy in a dramatically better position than Delta did and thus didn't need to undergo nearly as much capacity reduction as Delta. As we now see, AA, just one year out of bankruptcy, is by some estimates now projected to be pacing roughly the margins it took Delta several years to build to.
Fear, fear, fear.
