SCL, LAN's home, is a fairly small market. The 763 is much better sized for a market the size of the markets in western S. America than the 332 which is the primary widebody in TAM's fleet. The 763 w/ winglets competes fairly well on costs and still can easily carry 40-50K pounds of cargo even on 4000 mile segments.
Latam says that they will make a decision on simplifying their longhaul fleet - apart from the 340s that were already planned to leave JJ's fleet.
BTW, TAM's in-flight magazine - which has alot of duplicate content with LAN's this month - features a series of articles about the newly formed holding company. They have side by side English and Portuguese or Spanish.
Tom,
Since AA and B6 combined plus AE operate about 55% of all JFK slots and 75% of all slots operated by the US carriers (since about 25% of JFK's slots are held by foreign airlines), there would be antitrust issues - the same ones that people want to raise if DL and AA attempted to merge. There would have to be divestitures.
It also doesn't change the fact that LGA is the preferred airport in the NYC area for every market that can be served from LGA with JFK and EWR vying for 2nd place for markets that are also served from LGA and JFK 2nd for markets that cannot be served from LGA.
B6 has a very small presence at LGA and half of their presence came from buying very high priced slots as part of the DL-US slot deal. AA still has enough slots at LGA that they could mount a reasonable defense on their own and combined w/ large RJs, that might be their salvation in NYC. If being largest does matter - and the jury is still out on that - then it is doubtful that AA plus anyone can grow large enough to mount a defense against DL at LGA now. If DL deploys a number of their 717s in LGA to provide a mainline product, then it will be even harder for anyone else to provide a competitive product.
It also still doesn't change that B6's non-fuel costs are about 10-15% lower than any of the network carriers - including what AA is proposing post BK - meaning it would be impossible for many of B6's flights to work under AA's cost structure. The only way you could keep B6 is if it were a separate subsidiary of AA and it isn't clear that the pilot contract would allow that.
NYC is no different than other parts of AA's network - they will be smaller than UA and DL no matter what mergers might take place (and that includes AA/US where there is certain to be rationalization of the networks which people use while arguing for the basis of the merger and then at the same time add AA and US' current size together to say they will be the largest).
AA has to figure out how to use what it has to generate maximum revenues and hang onto the highest revenue business in the industry.
Even with the announcement regarding JFK-LAX and the 321, there still isn't anything that says that AA can't do that... they just will be walking away from a significant portion of leisure customers in a market where AA has always been the largest. It is not known long-term if AA can be the brand of preference for premium customers while not fully competing for all of the leisure passengers.
If you believe that AA should go after B6 - even if they must resolve the antitrust issues - then you also have to believe that AA has to compete for every leisure passenger in the JFK transcon markets. Based on AA's strategy with the 321, they do not appear to be doing that.
