There have been many improvements at the Rocky Point airport over the last year. There is now a daily flight between Hemorsila and Rocky Point with the first regularly scheduled International flight between Los Angeles and Rocky Point to begin October 30th. Read more about this on the International Airport update page of this website..
Here is some general information but I cannot guarantee the accuracy at this time.
