What's the difference between the ICAO and the IATA? Why do they have separate airport codes and when are the ICAO airport codes used? I've only seen the ICAO codes used for MCDU/FMC inputs...I'm sure they're used in other scenarios but when? Thanks.

As a general rule, IATA codes are used on the passenger side (timetables, reservations, etc.) and ICAO are used on the operations side.

IATA has to do with the commercial aspect of Aviation, ICAO has to do with the regulatory, standards, and operations aspects of aviaiton. As a result IATA codes are used for passenger reservation systems, ticketing etc etc, and ICAO codes are used for operations, flight planing, navigation, etc etc..
