Query: airports in london
Response: Found the following airports: London (YXU/CYXU), Luton (LTN/EGGW), Gatwick (LGW/EGKK), City (LCY/EGLC), Heathrow (LHR/EGLL), Stansted (STN/EGSS), East London (ELS/FAEL) and Groton New London (GON/KGON)

^ names like "city" are going to be a problem here. Does travelocity have an "all london airports" meta-airport? Most flight search engines I've used do.
