I've got hundreds of 'em. Schubak, Herpa, Lesney (Matchbox), Bachmann, Wooster, Dragon, kits, old colors, new colors, companies gone (Eastern, Western, PSA, AirCal, etc.), planes gone. I first got "hooked" back when airlines used to give them out in First Class. After they quit this practice in the early '80s, I kept up, and like seawolf, just bought the companies and aircraft type I had been on. Used to be a great little shop at Frankfurt airport that had every plane and company in the skies! Although the detail was not as sharp as say Herpa, I always like Schubak as they were all the same scale so when you lined them up you could really sense the difference in aircraft sizes.
FYI, there's a nice shop in United's terminal at SFO that carries a great selection of these and other airline "logo" stuff.
