Kuala Lumpur is a large city in Malaysia. Being the capital city, Kuala Lumour boasts very high business and tourism ratings that regulary exceed 300 or more each. A popular city to fly to, but not too popular as a starting hub due to it's slightly isolated location in South East Asia.
The default airport here is Kuala Lumpur International Airport (KUL).
In real life, the name "Kuala Lumpur International Airport" has switched airports in 1998. When the new and more modern airport took on the name, IATA and ICAO code and almost all international and domestic flights, the old airport was renamed to Sultan Abdul Aziz Shah Airport, (better known as Subang Airport) and given a new IATA code (SZB). Today, Kuala Lumpur International Airport has become the international gateway into Malaysia while Subang Airport serves primarily domestic routes within Malaysia using only turboprop airliners.
Because it is not as popular as New York or London, taking this place as a main hub is a good option. However, competition can still get intense due to it's high ratings. It's slightly isolated position means long ranged aircraft will become a necessity once all the short to medium haul routes are opened. It is recommend that the player act fast in trying to open as many routes as possible before other players step in, to try to deter other players from monopolising routes from Kuala Lumpur. Cargo routes are generally not a wise option for beginners, since long ranged cargo planes don't exist early in the game thus limiting the number of routes one can open. However, there are still many middle level cities like Chongqing, Busan, and Manila that can be used to sustain thriving cargo operations in this city.
The city's main airport can attain maximum slot usage within 20 to 30 years from 1960. However, due to it's slightly isolated location in South East Asia, a second airport will usually be unnecessary as the maximum slot usage will usually not exceed 1000 (level 4). Hence, building a second airport here is not recommended. Purchase of the main airport, however, is a good idea as it can bring it large profits.
The best passenger planes to similar sized large cities are usually the Airbus A380 or the Boeing 747. For flights to medium sized cities, smaller capacity planes like the Boeing 767, Airbus A300 and the Ilyushin IL-62. Smaller sized planes (e.g. Boeing 737 and Airbus A320) can be used to other nearby small or medium sized cities to earn a decent profit. For cargo routes, any planes are suitable as long as the satisfaction is high at the time of purchase.
