God, Padcrasher, you and your "emplanements."
Every time you want to show that Delta is gaining, you resort to telling us that Delta's emplanements to Latin America or wherever else are increasing.
Again and again, however, we try to remind you that "emplanements" mean nothing. All one emplanement means is that Delta had an additional boarding that they didn't have before. In this situation, it is no surprise that Delta has increased its boardings because they have added RJ flights far in excess of the number of mainline flights that they've eliminated.
It is a far leap, however, from having a greater number of emplanements to increasing market share. In absolute terms, it seems more likely that Delta's market share has remained flat or actually fallen. The latter seems even more likely because replacing a mainline jet with 120 seats with two RJ flights with 50 seats would result in a loss of seating capacity in any particular market served from DFW. Hypothetically, if AA can fill one 120-seat jet and Delta can fill both RJ flights to a particular destination, AA would still have a greater share of the market with only one emplanement.
Last year before Delta started its RJ push, I determined what AA's market share at DFW was vs. Delta's. I did that by going to the DFW Airport site and downloading the passenger number statistics. I did this because someone on another board was making the specious claim that Delta had increased its market share at DFW. What I found instead was that Delta mainline had shifted much of its capacity to Delta Connection carriers without increasing its market share at all.
I don't have the time to do that now and I suspect it would be much harder to do since one would not only have to count the passenger numbers of Eagle into the American total, but the passenger numbers of TWA, of course, only those flights that AA retained. Since the DFW Airport report only breaks down the numbers by airline and not flights, the best one could probably do is compare AA's market share to Delta's without the TWA LLC data.
In any case, I am assuming that AA increased its market share last year because of the addition of certain routes like DFW to St. Louis, among others.
