Mmmm low cost in South America.
I always think of low cost airlines as starting up operating 737-200's or something like that-you know old work horses that are having the life beaten out of them in a final fling.
Having been to South America twice and noting what aircraft I flew on- 737-200 and 727-100/200 (one was older than I was at the time) the standard carriers were flogging dead horses so what would low cost start ups use-guess they would have to drag out Dakotas-the mind boggles.
