There is a new trend toward alliances and something called "codeshares". Now, let's say I want to fly from Atlanta to Kuwait City. I call up Delta and tell them this; they then in turn book me on a Delta flight to Paris(lets call it Delta Flight 14) and on a connecting alliance Air France flight from Paris to Kuwait City. However the Air France flight is ticked as a Delta codeshare flight(call it Delta 9876). To the passenger it appears as if he will be flying on Delta all the way to Kuwait City, but Delta doesn't actually have to fly the route, saving it a lot of money on what would be a losing route for them.

Make sense?
