Thanks for your feedback. I didn't know AA was third at FLL, so thanks for correcting that. Last time I was through there though it seemed like they only had a coupla gates. Still, I don't deny that seasonal traffic still plays a heavy part in deciding routes to South Florida. But that's changing.
Regarding population, I erred when I brought up tv markets...here are market rankings according to Arbitron which is primarily a radio rating service, though used by tv too (not like Nielsen though).
The number to the right is the population over the age of 12 in the "metro".
1 CM New York 15,097,900
2 CM Los Angeles 10,407,400
3 CM Chicago 7,476,700
4 CM San Francisco 5,951,800
5 CM Dallas-Ft. Worth 4,418,400
6 CM Philadelphia 4,221,400
7 CM Houston-Galveston 4,055,300
8 CM Washington, DC 3,928,700
9 CM Boston 3,839,000
10 CM Detroit 3,811,500
11 CM Atlanta 3,617,400
12 CM Miami-Ft. Lauderdale-Hollywood 3,377,400
Here's the Palm Beach market's rank:
47 CM West Palm Beach-Boca Raton 1,031,900
Add Palm Beaches and Miami/Fort Lauderdale and your number comes up at just a tad under that of the DFW metro. I think you're ranking Dallas as a stand-alone city, which would be like ranking Miami as a standalone. Fort Worth completes the picture and makes the area the super-city that it is.
Personally, I don't think UN numbers are very accurate to apply to US economic centers.
I'm convinced that if the everglades were dry land, Miami would sprawl all the way to the west coast of Florida, a veritible East Coast version of Los Angeles.
Let's hope THAT never happens.
