Once again, B6 has become the largest airline in NYC-FLA and BOS domestic; AA is trying to compete with the highest costs in the industry which makes them the first to lose money competing with B6 at B6's costs. Not surprisingly, 75% of AA's NYC-FLA revenue comes from its backbone route of LGA-MIA with a minimal presence only in just a couple other markets. You do realize that DL, not AA, now carries more local passengers in JFK-MIA?
Revenue and traffic information by market is not really proprietary since airlines are required to report it to the DOT.
IN BOS, AA has been the most aggressive in pulling down its domestic network against B6's growth. I find it hard to see how you can say that B6 has not driven AA out of most the markets from the NE in which B6 competes.
Of course AA is pulling out of BOS-DCA because they can't make money. After the downsizing that has occurred at BOS, AA does not have the critical mass to fly point to point markets on RJs even against US' mainline jets. Given no other viable options for new service from DCA - any of which likely are flown by US which has a cost advantage to AA - AA had no choice but to figure out how to get some slots.
B6 finds it more valuable to develop a presence in DCA using the AA slots than to hold onto the least profitable half dozen flights from JFK; as a bonus, AA agreed to codeshare on B6 which means that AA can at least put its code on B6's flights in the markets which AA has exited. AA does have the potential to cut its decline in NYC where it is now the #3 carrier behind CO/UA and DL and where DL has been very aggressive in building JFK; with a half dozen JFK slots, AA might be able to enter a few new markets and share the risk on those markets with BA and IB under the new joint venture. But AA is still competing against lower cost rivals CO and DL from NYC who are already larger in most markets except for London, which those carriers have both entered and are doing well in. But let's be clear that American Eagle's presence in the NE has shrunk and is shrinking in light of lower cost competition and with AA and AE's exit from many markets in the NE, AA has no choice but to codeshare to maintain ANY presence - and that work is not being done by AA employees.
Now, tell me how AA wins in this? At best, this is a "lose less" or "cut your losses" strategy for AA.
As for TW, it is well known that they were an aggressive discounter throughout the US but even with their small size in the Caribbean, they were already negatively impacting AA"s profitability in the region where there was very little low cost competition 10 years ago. AA clearly benefitted everywhere - along with the rest of the industry - with elimiating TW's aggressive discounting but the reality is that if AA had known 9/11 was coming, AA would have allowed TW to fail in the post 9/11 crisis in the airline industry.
No, AA won't tell you or anyone else that they bought TW to eliminate competition but given that there is not much left of TW 10 years later and AA moved very quickly to eliminate the low fares which TW once offered, it isn't hard to put 2 plus 2 together.
