Azerbaijan Airlines (AZAL) was established in 1992 and began international routes to destinations like Dubai, Istanbul, Tehran, and London in 1994. It suspended some regional services in 1998 due to financial issues. Baku Heydar Aliyev international airport serves around 1 million passengers annually and was previously known as Bina international airport. In 2011, AZAL received the European service standard from the European Economic Chamber for its high service standards.
