Alright...that is a good thing. There are probably 4 or 5 more cities we could serve in Brazil; that is, if we had the planes. We know about Sao Paulo, but maybe Brasilia, Belo Horizonte, Manaus (could be served with a 757) and Belem (maybe a 757). There are several others but we would need 767s or larger to serve them.
I can say with 100% certainty that US will not serve any of the above mentioned cities other than GRU and GIG even if it had an abundant supple of 757/767s
Doesn't sound like a good thing to me. One of the reasons US liked Brazil is because of its high-barrier to entry which helps keep airfares up. Having to compete with Delta or American or TAM running increased frequencies or serving secondary Brazillian markets can only drive down fares and likely traffic on US.
In addition to Rio, Sao Paulo, and Recife, we (AA) are adding flights to Belem and Brasilia soon. Just announced. (Or, that may be adding Recife also. I don't follow it that closely because I won't live long enough to proffer for International.)
I'm confused. Why would lower fares drive down traffic to Brazil? Wouldn't lower fares help increase traffic?
As for US, every time I've looked, US' business class fares on CLT-GIG nonstop are fairly high (as expected) but US' connecting fares from major east coast cities are farily affordable compared to AA's fares. Of course, the O&D between CLT and GIG is very low, so US isn't getting very many of those expensive nonstop fares - most of US' traffic is connecting to/from somewhere else, meaning US' yields to GIG can't be very high as it is.
