, ORD also has non-stops to IST, Turkish 3x a week (and before 9.11 MIA did too
, Northwest Airlink.
, your information is 100% correct, but, just to add, the stop is changing back to FLL this fall, so FLL will be the only city with non-stop from CPT, and ATL will be the only one with service too. And you are right about STG. DL did fly JFK-STG at one point, but it didn't work out.
, your right, not many cities have Zacatecas service. From what I found, only ORD also has ZCL service. LAX might, but I only checked for weekend service.
Here are some others I can think of:
San Juan to Herrera, Dominican Republic
JFK to Luxeumburg
JFK to Georgetown, Guayana (though MIA gets GEO this winter)
JFK to Nice, France
JFK to Cairo, Egypt
JFK to Casablanca, Morroco
Miami to Cordoba, Argentina (late summer 2002)
Ft. Lauderdale to Walker's Cay, Bahammas
Opa Locka (Miami) to Cape Haitian, Haiti
Watson Island (Miami) to Bimini, Bahammas
Anchorage to Petropavlovsk-Kamchatsky, Russia
Los Angeles to Guangzhou, China
Los Angeles to Melbourne, Australia
Los Angeles to Auckland, New Zealand
Los Angeles to Noumea, NC
Los Angeles to Nagoya, Japan
Los Angeles to Fukoka, Japan (??)
