YMQ is a catchall for the airports in the Montreal metro area (similarly, LON is used for London, TYO for Tokyo, NYC for New York, etc.).
YUL is the main international airport (Pierre Eliott Trudeau)
YMX is Mirabel airport (cargo only right now, as far as I know)
YHU is Saint-Hubert, used for smaller planes on shorter routes from within the province of ...
It just fails to beat your 'Frankfurt' Hahn, but Lydd Airport is also called London Ashford Airport, even though it's 117 km from central London. Given usual traffic conditions, that's probably a longer drive with a car than from Hahn to Frankfurt.
Babies and small children at the airport
Did you bring your own baby food to the airport? You can have it heated in all restaurants at the airport. Our staff are happy to be of assistance. Microwave ovens are available in most of the airport restaurants.
It's 1,5 km on foot (1,23 km in a straight line) from the Gibraltar International Airport terminal to the beginning of the Main Street. Although Gibraltar's population is officially only 32k, so I don't know if it's decent-sized enough for the purpose of the question ;)
It's a bit of a cheat, but Bozeman Yellowstone International Airport (BZN) is approximately 150 km from the geographic center of Yellowstone National Park. Of course, Yellowstone National Park is huge; the closest point in the park is "only" about 75 km away as the crow flies, while the farthest point is about 200 km away. The park headquarters are 96 km ...
In Pisa, Italy, there are less than 3 km between the airport terminal and the Leaning Tower of Pisa which is on the opposite side of the city.
In Ponta Delgada (São Miguel Island, Azores) there are 4 km between "city center" and the terminal which is on the furthest end of the runway. But it's about 1,5 km to the closest end of the runway.
There are a lot ...
It's surprisingly close for a European city, but Reykjavík Domestic Airport (RKV) is only 2.1km from the city center; the closest edge of the airport only half that distance.
Do not confuse it with Keflavík International Airport (KEF) which most people use to fly to Reykjavik; that lies at a comfortable 50km distance.
Some airports report themselves how many transfer passengers they have (or at least what's the % of all passengers). E.g. Schiphol (AMS) had 71.053 million passengers in 2018, of which 36.6% were transfers, for a total of 26 million transited passengers. Heathrow claims a figure of 24 million transited passengers, 30% of its total.
According to the paper ...
Honorable mention should be given to Mexico City. The international airport is about 5km from the city center. That is not the shortest distance, but Mexico City is one of the bigger cities of the world. The airport is completely surrounded by urbanized greater Mexico City. It wasn't that way when the airfield was first built.
Taipei's smaller, more central and less internationally known airport (Taipei Songshan Airport) is very, very close to the city center at about 3km - 4.5km depending on what you consider the center of Taipei.
It's also the only city on this list that is a megacity and a capital of a country.
According to Google Maps, the distance from Bangkok to U-Tapao is upward of 170 kilometres by road, as shown in the screenshot below. The direct distance, as pointed out in a statement by Eva Air (in the quote below, in bold) is about 140 kilometres.
There are plans for U-tapao Rayong-Pattaya Airport to become Bangkok's third ...
CXH must be it. Not sure what the center of Vancouver even is, but it's 500m from Waterfront Station which is the most important transit hub in Vancouver and 800m from Vancouver City Center station which, I guess, could be called the center of the city? It is a floatplane terminal, sure, but it has domestic and international flights both. There are more than ...
I like the previous answers as well, but I'd put Gibraltar as a contender. It literally bisects an urban thoroughfare and I walked from the major airplane to my hotel with my luggage and could walk from the airport to any location in the city - if you happen to not be able, there are taxis, etc.
I just tried. It is surprisingly easy, and I would totally recommend it even if you have only 4 hours between flights.
I will suppose that like almost everyone coming from an international flight you are at Terminal 3. From the arrivals, go down to the ground floor, where the local buses are, and walk to the right:
After the last bus stop there is still a ...
Allow me to nominate Burbank (Bob Hope) Airport. Burbank is a suburb of Los Angeles with over 100,000 population in its own right. The airport is downtown, to the extent downtown is meaningful with sprawl.
Not the closest, but from Da Nang International Airport (DAD) to what OSM calls the city center is only about 2.1km on foot. Google map couldn't point out the true center but you'll need a walking distance of 2.5km to the central railway station, 2.5km to the central Dragon bridge and 3.2km to the central market
Da Nang is the largest city in central ...
It's probably not the sort of airport you're thinking of, but in Washington State, it's 800 meters from Kenmore City Hall to the docks of Kenmore Air Harbor. And yes, it does have an airline operating regularly scheduled flights: Kenmore Air.
(Also in the Seattle area: the docks of Lake Union Seaplane Terminal are about 1100 meters from the Space Needle, ...
