There's still several that may be added but based on whether I do the trips or not and those include CTG, PRG, EDI or MAN, HAV, RAK and DUB.

So at age 23 by the end of the year I'll have at least 92 unique airports visited (81 currently). Not bad.

Best: Singapore with Seoul a close second.
Worst: Ever, the old DTW terminal NW used prior to McNamara. Current, EWR or LGA
