for some strange reason, every time i choose airport activity for  
puerto rico and the virgin islands i keep getting this message.  
unknow or invalid airport code; using the correct icao 3 or 4  
digit airport code; not iata code. can someone suggest a  
solution to this anomaly?

new member, great service (free) and lots of very knowledgeable  
and helpful aviation friends.

thank you very much
