I am trying to see if there are direct flights from any US city to Puerto Ordaz or Ciudad Bolivar. Basically, I am planning to do a standard Angel Falls tour which typically starts from either Puerto Ordaz or Ciudad Bolivar. All flights from US seem to go to Caracas only. I don't unnecessarily want to connect via Caracas if there might be any direct flights to Puerto Ordaz or Ciudad Bolivar. Any idea about this?
