I live in San Diego, and am going RT to Buenos Aires (coach) in less than two weeks for a South America/Antarctic cruise on the Star Princess. I, too, have great concerns about the travel, as it is over three hours to Houston, and then over then hours to Buenos Aires. However, I think it will be the trip of a lifetime, and I will let you know how bad the plane travel was when I return. We will be going on Continental (which, at my last flight with them had fairly comfortable seats and legroom compared to some of the others). Will also let you know if that still holds true.
