DC

Clearly I do much better with state capitals, since over half the countries I've visited haven't included the capital. Furthermore I haven't been to a new national capital since 1992.

Reykjavík (sitting on a plane on the tarmac for refueling)

If this was the main international airport, it is near Keflavik, an hour away from Reykjavik by car. So, likely you do not get this one

[ag]

Istanbul (transit)

Unless you are a hundred years old, it was not the capital when you visited

[Mr. Morden]

Only counting cases where I left the airport (and this is, I think, the order in which I first visited them):

Washington, DC, USA
Canberra, Australia
Beijing, China
Jakarta, Indonesia
Kuala Lumpur, Malaysia

If you count airport layovers:
London, UK
Bangkok, Thaliand

[Lachi]

Canberra, Australia
Tokyo, Japan

I mean, I paid nearly a hundred bucks for the two of us go from the airport to Reykjavik and back by bus (and that was with a good discount). You can't get it that cheap

[Peanut]

Mexico, DF

DF has ceased to exist for nearly 3 years now.

Well, Mexico City. I've been calling it DF since forever and since, well, I don't usually spend a lot of time talking about Mexico's capital, I keep on stubbornly calling it DF. Old habits die hard.

[Landslide Lyndon]

Istanbul (transit)

Unless you are a hundred years old, it was not the capital when you visited

It is in our hearts.
