Who here has taken a trip (either personal or business) and has flown different airlines for one part of the trip. Do they switch your baggage automatically? How does the ticketing work? I can see the switching the bags working but I am not sure how the ticketing work? If I check in on Delta and have my second leg on US Air how do I get my ticket for US Air? I have flown many times before but just not on multiple airlines in one day.
