YYC is the airport's IATA code
The Y in the airport designation originally meant that the weather station was co-located at the airport. The Yxx identifier was for an airport, and Zxx was for an aerodrome. Under ICAO, all Canadian airport codes start with CY or CZ. Therefore, Calgary International Airport has three identifiers: TCLID-YYC, IATA-YYC, and ICAO-CYYC.
The airport is branded as YYC Calgary International Airport and is located approximately 17 kilometres (11 mi) northeast of downtown Calgary, Alberta, Canada. It covers an area of 20.82 square kilometres (8.04 sq mi; 5,144 acres; 2,082 ha). With 18.9 million passengers in 2024, it is the busiest airport in Alberta and the fourth-busiest in Canada by passenger traffic.
The airport features two north-south parallel runways and one intersecting runway. The parallel runways are 17R/35L (west) and 17L/35R (east). There are also two hotels located on-site: the Calgary Airport Marriott In-Terminal Hotel and the Delta Hotels by Marriott Calgary Airport In-Terminal.

The first Y may indicate a co-located weather station
The airport code for Calgary International Airport is YYC. While the exact reason for this is hard to pinpoint, one theory suggests that the first "Y" in the airport code might indicate that there was a co-located weather station at the airport.

Canada's airport codes usually match the ICAO code
Canada is known for its airport codes starting with the letter Y. However, there are airports outside of Canada that also use the letter Y at the start of their airport codes. For example, YAI is the code for General Bernardo O'Higgins Airport in Chillán, Chile.
There are two entities responsible for allocating codes to airports. The first is the International Civil Aviation Organization (ICAO), which assigns four-letter codes to public and private airports. It is mostly for official use, such as air traffic control, flight plans, and airline identification. In most cases, the first letter of the ICAO airport code indicates the region, the second letter refers to the country, and the remaining two letters are assigned to a specific airport.
The second entity is the International Air Transport Association (IATA), the trade association of the world's airlines. Mainly used for commercial purposes, the three-letter IATA airport codes can be found on plane tickets, boarding passes, baggage tags, and domestic flight numbers. Due to the three-letter character limit, not all IATA codes are unique, so there are some instances where two airports could have the same code. The last three letters of an ICAO code can sometimes be the same as the IATA code, but it is not always the case.
Canada and the USA are generally exceptions in that their codes are usually the same. Add a 'C' to Canadian IATA codes to get the ICAO code, and a 'K' to US ones. For example, Calgary International Airport's IATA code is YYC, and its ICAO code is CYYC.
