An IATA airport code , also known as an IATA location identifier , IATA station code , or simply a location identifier , is a three-letter geocode designating many airports and metropolitan areas around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.

The surface bedrock under the Miami area is called Miami oolite or Miami limestone. This bedrock is covered by a thin layer of soil, and is no more than 50 feet (15 m) thick. Miami limestone formed as the result of the drastic changes in sea level associated with recent glacial periods , or ice ages . Beginning some 130,000 years ago,

1056-506: A wealthy Cleveland native, was the original owner of the land upon which Miami was built. In the late 19th century, the area was known as "Biscayne Bay Country", and reports described it as a promising wilderness and "one of the finest building sites in Florida". The Great Freeze of 1894–1895 hastened Miami's growth, as the crops there were the only ones in Florida that survived. Julia Tuttle subsequently convinced railroad tycoon Henry Flagler to extend his Florida East Coast Railway to

Hurricane season officially runs from June 1 to November 30, although hurricanes can develop beyond those dates. The most likely time for Miami to be hit

1248-499: Is GSN and its IATA code is SPN, and some coincide with IATA codes of non-U.S. airports. Canada's unusual codes—which bear little to no similarity with any conventional abbreviation to the city's name—such as YUL in Montréal , and YYZ in Toronto , originated from the two-letter codes used to identify weather reporting stations in the 1930s. The letters preceding the two-letter code follow

All non precleared international flights are processed in Terminal 2 and arrive into gates C21, C23, C24 and C25. The airport incorporates two cargo areas, North Cargo and South Cargo. The North Cargo terminal area

1632-544: Is available. However, many railway administrations have their own list of codes for their stations, such as the list of Amtrak station codes . Airport codes arose out of the convenience that the practice brought pilots for location identification in the 1930s. Initially, pilots in the United States used the two-letter code from the National Weather Service (NWS) for identifying cities. This system became unmanageable for cities and towns without an NWS identifier, and

Throughout the latter half of the twentieth century, Miami experienced a certain amount of stagnation in its population, with expansion slowing during

2688-1125: The Appalachians (but Eastern started a Super Constellation nonstop to Newark in 1958). The next airline (aside from United's takeover of Capital in 1961) was Delta Air Lines in 1970. In April 1969, nonstops didn't reach beyond New York or Atlanta, and Chicago was the only nonstop west of the Appalachians. RDU's first scheduled jets were Eastern 727s in 1965. In the 1970s, the last decade before airline deregulation, Piedmont connected RDU to Charlotte , Greensboro , New Bern , Norfolk , Richmond , Rocky Mount , Washington, Wilmington and Winston-Salem . United flew to Asheville, Charlotte, Huntsville and Newark, while Eastern flew to Atlanta, Charlotte, Miami , New York, Philadelphia , Richmond and Washington, and Delta flew to Chicago and Greensboro.

American built

2784-561: The Canadian transcontinental railroads were built, each station was assigned its own two-letter Morse code : When the Canadian government established airports, it used the existing railway codes for them as well. If the airport had a weather station, authorities added a "Y" to the front of the code, meaning "Yes" to indicate it had a weather station or some other letter to indicate it did not. When international codes were created in cooperation with

2880-601: The Revolution in 1959, many wealthy Cubans sought refuge in Miami, further increasing the city's population. Miami's national profile expanded dramatically in the 1970s, particularly in 1972. The region hosted both the Democratic and Republican National Conventions in the 1972 Presidential election .

Miami grew by 34.3% in the 1950s and 1960s as its population reached 334,859 at the 1970 census . In the next three decades, it only grew 8.2%. By the time of the 2000 census , Miami's population stood at 362,470. In the 2000s and 2010s, spurred by high-rise construction in Downtown Miami, Edgewater, and Brickell, Miami's population began to grow quickly once more. An estimate by

3456-492: The 2020 census, it was 52,447, only 11.7% of the population. Reasons for this include high costs in areas such as Liberty City and Little Haiti , compounded with gentrification . The non-Hispanic White population began to rebound in the twenty-first century, as the monolithically Hispanic areas in the Western and Central parts of Miami experienced population stagnation. This caused them to begin to be outweighed by migration into

3552-467: The American Community Survey found that the downtown population, from Brickell north to Midtown Miami, grew nearly 40% between 2010 and 2018. From 2000 to 2010, Miami's population grew by 10.2% and reached 399,457 in 2010. In the early 2010s, Miami's population crossed a milestone of 400,000 people.

3648-466: The Census Bureau reported Miami's population as 45.3% Hispanic, 32.9% non-Hispanic White, and 22.7% Black. Miami's explosive population growth has been driven by internal migration from other parts of the country, up until the 1960s. From 1970 to 2000, population growth in Miami was stagnant, as non-Hispanic White Miamians left and significant immigration from Latin America, particularly Cuba , made up

3744-494: The Downtown region, from Latin America and the rest of the United States. This caused the non-Hispanic White population to rise from a nadir of 11.8% at the time of the 2000 census to 11.9% at the time of the 2010 census . After this, the non-Hispanic White population grew significantly faster than Miami as a whole did during the 2010s. In the 2020 census , non-Hispanic Whites were 14.0% of the population of Miami and numbered 61,829,

A Spanish mission was constructed one year later. Spain, and briefly Britain , ruled Florida until it ceded it to

4128-505: The U.S. For example, several airports in Alaska have scheduled commercial service, such as Stebbins and Nanwalek , which use FAA codes instead of ICAO codes.

Julia Tuttle , a local citrus grower and

4416-933: The United States that will be most affected by climate change . Globally, it is one of the most at-risk cities, according to a 2020 report by Resources for the Future . Global sea level rise , which in Miami is projected to be 21 inches (53 cm) to 40 inches (100 cm) by 2070, will lead to an increase in storm damage, more intense flooding, and will threaten Miami's water supply. Other potential impacts of climate change include higher hurricane wind speeds and severe thunderstorms, which can bring about hail or tornadoes. Some protective efforts are in place, including nourishing beaches and adding protective barriers, raising buildings and roads that are vulnerable, and restoring natural habitats such as wetlands . Miami Beach has invested $ 500 million to protect roads, buildings, and water systems. Real estate prices in Miami already reflect

4512-481: The United States, because "Y" was seldom used in the United States, Canada simply used the weather station codes for its airports, changing the "Y" to a "Z" if it conflicted with an airport code already in use. The result is that most major Canadian airport codes start with "Y" followed by two letters in the city's name (for example, YOW for O tta w a , YWG for W innipe g , YYC for C algar y , or YVR for V ancouve r ), whereas other Canadian airports append

For instance: Or using a code for the city in one of the major airports and then assigning another code to another airport: When different cities with the same name each have an airport, they need to be assigned different codes. Examples include: Sometimes,

4800-418: The airport's former name, such as Orlando International Airport 's MCO (for Mc C o y Air Force Base), or Chicago's O'Hare International Airport , which is coded ORD for its original name: Or char d Field. In rare cases, the code comes from the airport's unofficial name, such as Kahului Airport 's OGG (for local aviation pioneer Jimmy H ogg ). In large metropolitan areas, airport codes are often named after

4896-595: The airport's hub carrier from 1995 until 2003. In 1995, Midway had flights to Boston , Hartford , Long Island , Newark, Newburgh, New York , Philadelphia and Washington in the Northeast, and to Fort Lauderdale , Jacksonville , Orlando , Tampa and West Palm Beach in Florida .

5088-472: The airport. The Vision 2040 Master Plan details several major improvements that are aimed to be made by 2040. Proposed in 2017 by the RDU Airport Authority, the plan calls for major additions and renovations of current facilities at the airport. This includes the construction of a consolidated rental car facility, an on-site hotel, expansion of parking lots, expansion of both terminals, improvements to

5184-468: The airport. Several mainline flights were also dropped and service to other cities was reduced or downgraded. Other airlines also cut flights and destinations including United Airlines and US Airways . Also in 2008, the airport was modernized; the current rebuilt Terminal 2 opened, on the site of the old Terminal C that was built in 1987. The rebuilt was completed in 2011, and was designed by Fentress Architects . By 2010, RDU's traffic began to recover. In

5280-457: The aquifer, it is not possible to dig more than 15 to 20 ft (5 to 6 m) beneath the city without hitting water, which impedes underground construction, though some underground parking garages exist. For this reason, the mass transit systems in and around Miami are elevated or at-grade . Most of the western fringes of Miami border the Everglades , a tropical marshland covering most of

By 15,000 years ago, the sea level had dropped 300 to 350 feet (90 to 110 m) below the current level. The sea level rose quickly after that, stabilizing at the current level about 4,000 years ago, leaving

The non-Hispanic Black population of the city of Miami peaked in 1990 at almost 90,000, making up nearly a quarter of the population of Miami. Since then, Miami's non-Hispanic Black population has experienced a precipitous and steady decline. In

6144-919: The end. Examples include: A lot of minor airfields without scheduled passenger traffic have ICAO codes but not IATA codes, since the four letter codes allow more number of codes, and IATA codes are mainly used for passenger services such as tickets, and ICAO codes by pilots.
