Can anyone confirm that IAH-GRU has been upgraded to 764 year round? It appears to be on the system as far out as ive checked. Does anyone have an idea how much money CO bring in on the IAH-GRU flights? How do the IAH-GRU flights compare to other international money makers for CO? Also, does anyone know the aproximate percentage of passengers is on the IAH-GRU route that is originating in Houston, versus connecting passengers? Thanks so much, also any other information you all would have regarding the IAH-GRU flight would be appreciated.
