DIA is in the Denver city limits, but the land was annexed from a neighboring county. The city limits of Denver are roughly a square, with a narrow corridor on the northeast corner connecting to another suare which is DIA.
In some cases the airport is in a different state. Cincinnati’s airport is in northern Kentucky, and of the three airports serving Washington DC, two are in Virginia and one is in Maryland.
Portage Wisconsin
Calgary’s airport is within the city of Calgary.
In Australia, the third busiest airport is within the city it serves (Brisbane), but the first two (Sydney and Melbourne) are not. That’s as a result of the cities of Sydney and Melbourne being small in area, and Brisbane being quite large.
The fourth largest international airport (Gold Coast) is only partly in the city of the Gold Coast, Queensland. The southern end is in Tweed Shire, New South Wales, so that in summer the airport is two time zones as well as in two states: you should change your watch one hour backwards or forwards as you go down the runway.
But the land that Reagan airport is on used to be part of DC. One might say that the airport was within DC city limits up until the mid-1800s.
And a proper, standalone Giordano’s pretty close too. Good information to have, depending on the length of your layover. 
Well, not the airport (since it was before airports were invented), but the site of the airport was in DC – but not in the then city of Washington. It was in Alexandria County. outside the city of Alexandria.
That’s what I meant the to convey. Dumb joke on my part.
Well, it’s already been pointed out that both NYC airports are indeed in NYC (Queens), but Newark (Liberty) International Airport is in Newark NJ…and Elizabeth NJ (roughly split in the middle, North in Newark, South in Elizabeth), so perhaps that counts.
Some cities that cover unusually large areas almost need to have their airports within the city limits to avoid being extremely inconvenient. Examples include Louisville KY (399 sq. mi.), Anchorage AK (1961 sq mi), Juneau AK (3255 sq mi), and Oklahoma City, OK (621 sq mi).
I think that’s part of the reason why so many cities have their seaports or train stations convenient to old-town or downtown.
The only city/town that I know of whose train station is outside the city is the smallish city of Fairfax, Virginia, and that’s because the town was already there when the railroads came and decided to pass it by :(, so they built a train station on the line and ran stagecoaches, then busses between it and downtown (on what is now Ox Road in Virginia).
Cleveland Hopkins International Airport (CLE):
• Cleveland Airport was opened in July 1925 and became America’s very first municipally owned airport.
• In 1930 it became the first airfield to install a lighting system, and during the same year, was also the first airport in the world to have an air traffic control tower.
• Hopkins Airport also initiated the very first radio communication system, passenger information boards, railway-air passenger services, air taxis and onsite paramedic unit.
Burke Lakefront Airport (BKL):
• Built in 1947, Cleveland Burke Lakefront Airport was the first downtown airport.
• Located along the rolling shores of Lake Erie (across East 9th Street is the Rock and Roll Hall of Fame).
Cleveland (Hopkins) is inside the city limits.
The Tulsa and Oklahoma City airports are both within their cities’ limits.
The old Kansas City Municipal Airport (now called Wheeler) and Denver’s old Stapleton Airport were within the city limits.
Reagan National is in Arlington county. The mailing address is Washington, DC. It is literally on the banks of the Potomac river. Swim across and you will be in DC proper.
Yes, but when that territory was in DC (between 1791 and 1846), the part of DC taken from Virginia and later given back to Virginia was organised as Alexandria County. It was only when that territory was given back to Virginia that part of Alexandria County was organised as Arlington County, and part was organised as the independent city of Alexandria. (Virginia has “independent cities” which effectively function both as cities and as counties.)
True, but the Oklahoma City airport (Will Rogers World :rolleyes: Airport) is only about 6 miles from downtown OKC. (As the crow flies.)
My mother was an airline stewardess in the early 1960s, and regularly flew into Midway. She said that it was her least-favorite place to land, because of the proximity of the residential areas to the airport – the planes took steep approach angles, and you were right over houses until moments before landing.
Chicago also had the small, primarily general-aviation Meigs Field within the city limits (it was right on the lakefront, just east of the Museum Campus), which had commercial (commuter airline) service, at least through the 1980s. In 2003, Mayor Daley had the runway at Meigs torn up in the middle of the night (after years of threatening to replace the airport with parkland).
Further to the San Jose situation… having it literally right downtown in such a large city (10th largest in the US) is part of what makes San Jose such a “no there, there” city. Buildings in the flight path (all of downtown, really) are restricted in height to (IIRC) 15 stories. Plus, San Jose is such a sprawling city, that it just doesn’t support much of a downtown. It’s supprising how much land within the city limits is still farmland, even today.
