>>1311990We use both but lets be fair here IATA is a hell of a lot easier to remember than ICAO
MAD = MADRID
LEMD = ?
LHR = London HeathRow
EGLL = ?
NRT = NaRiTa
RJAA = ?
HND = HaNeDa
RJTT = ?
if you travel often IATA just sticks better and the name is pretty easy to decipher especially if your'e traveling outside the US because US is just K plus the IATA
