Mark:
Having been at the last few Routes conferences I know that the fact that an airline and an airport have talked for 15 minutes there means next to nothing. Either side can request the meeting, so I would expect the BHX marketing folks to have arranged meetings with pretty much all the US carriers (and various Asian ones, and various European ones...). To give you an example of funky meetings at Routes 2004 (just one example among several): Delta and Doncaster. Guess who asked for that one? (Clue: not the airline).
