Here's CO. Sorry for the delay, but their "3 airlines in one" setup makes it more difficult to summarize their routes. (The 3 airlines are Continental, Continental Micronesia, and COPA.)

Even more than AA CO has a lock on Mexico, the Caribbean, and to a lesser degree South America. They have good but unusual connections to Asia though mostly Japan, And they are the only airline to fly to a lot of Pacific Ocean destinations. They also fly to Cairns, AU, again via Guam (and HNL.) Canada and Europe are strong, leaving Africa as the only hole in their otherwise overwhelming coverage (though the do fly to Tel Aviv.)
