Number 54 out of 382 Primary Airports in the country based on passenger boardings in 2004. (That puts it right behind Columbus, OH.) just under 3 million boardings, with a 5% growth over last year.
Since you mentioned DFW, they are almost exactly 10 times bigger, ranked number 4 in the US.
The largest NY airport is all the way down in 8th place.

Thanks for the stats on Love Field. I had no idea it had that much traffic. I like it because it's closer to Dallas and because it's not as busy.
