It seems that Karachi (KHI) has 2 airports when there should be one. There is both Jinnah and Quaid-e-Azam in the game and both have KHI for their IATA codes. See the quote from Wikipedia below:
Jinnah International Airport previously Quaid-e-Azam International Airport (IATA: KHI, ICAO: OPKC) is Pakistan's largest international and domestic airport. It is located in Karachi, Sindh, Pakistan, and is also commonly known as the Jinnah Terminal. The airport is named after Muhammad Ali Jinnah, who was also known as Quaid-e-Azam ("Great Leader").
