Names defined for an ontology of flight information. I got everything I could out of http://www.daml.org/2001/06/itinerary/itinerary-ont and http://www.daml.ri.cmu.edu/ont/AirportCodes.daml; these (and flight numbers added to this URL as flight identifiers) are what's left over. I'd be happy to drop this if anyone can point to an existing ontology with equivalent names. bob@snee.com
