Liege Airport, located in Liege, Belgium, is an international airport that has a rich history. The airport was first established in the early 1920s, when the city of Liege was looking for a new way to open up the city to the rest of the world. The airport was originally named the Liege-Melsbroek Airport, after the two villages that it was located between. The airport was then expanded in the 1930s and 1940s and became the main airport of Liege.

In the 1950s, the airport was renamed the Liege-Bierset Airport after the two villages that it was located between. The airport was then expanded again in the 1960s and 1970s, and it was granted international status in the late 1970s. The airport was then renamed the Liege Airport in the 1980s, and it is still known by this name today.

The airport code of LGG was determined by the International Air Transport Association (IATA). This code was chosen because it is the airport's location code, which is the first three letters of the airport's name. The airport is served by a number of airlines, including Brussels Airlines, KLM, easyJet, and Lufthansa.
