Every one of those flights has a terminus in North America. What about something like London-Sydney? Do other countries not like the super-long nonstop flight?
I saw that map and wondered how San Bernardino County figured into it. Huge land mass but isn't it mostly desert with Barstow the major city?
You forgot about the southwest portion of the county (Ontario, City of San Bernadino, Fontana, etc..) that borders LA. That's where all the people are. There are several towns in that corner that are over 100,000 people. Barstow actually isn't actually very much of the county.
