each airline is assigned a (or a set of) carousel(s) to use depending on gate/baggage office/carousel location. Having said that, each carousel might be shared by a set of airlines, and are used on a first-come, first-served basis. At smaller airports, there may be only one or two carousels total, so all airlines might use it first-come, first-served.
