I can't believe today Montevideo is still served with a HUGELY inconvenient stop in Buenos Aires. I don't know if a 767-300ER could be filled daily but the answer may be serving the market 4 or 5 times weekly. A 757 may be the answer, while I'm no fan of 8 hour flights on this plane, nonstop by 757 is better then nothing. AA should outfit some 757 with 767 style Business Class for service to Southern South America & Europe to cities that can't support a 767 like MVD, ASU, Belo, Edi and Birmingham, England. AA has been able to tap a huge market in South America previous opertaors in the area couldn't but there is still a niche market asjing for nonstop flights to Miami.
