And another thing.. The stars are sometimes common to more than one destination. eg BIG arrivals for LL and WU, and Alkin ones for KB and LC. The stars and designators are the same. Only the transitions after BIG or ALKIN are different.
As for airport codes I like the US way of doing this. ie, JFK (IATA) & KJFK (ICAO), SFO & KSFO and EYW & KEYW
(Key West). Who would have guessed EGGW was LTN instead of Gatwick. Don't guess is the answer I suppose. I know our system is geographically based but it is not easy to use.
