Edit airline details + CEO name

Didn't know that. Thought it was 2 or 3 letters/numbers.

So what's the difference between IATA and ICAO? What should be used for the game?

ICAO (International Civil Aviation Organization) is a UN-body which focusses on international harmonization of civil aviation regulations. 

ICAO codes are used for "official" purposes such as Air Traffic Control; E.g. flight plans use ICAO codes for airports and airline flight identification.

IATA (International Air Transport Association) is a trade association that focusses on making air traffic businesses safe, secure, reliable and efficient. 

IATA codes are mainly used for ticketing. E.g. travel itineraries use IATA codes for airports and IATA flight numbers.

I knew about the difference between these organisations, but didn't know what their codes were used for exactly.
