If you make a reservation with Copa Airlines in conjunction with another Star Alliance carrier, your baggage will be checked in after check-in to your final destination, unless the regulations apply in accordance with the Copenhagen Interline baggage rules. At your connecting airport (point B), you must pick up your luggage and reintegrate with the next airline – this means that you go to the baggage handover, then to the check-in desk of the second airline and check-in (payment of another fee for checked baggage) and then go through security again. Some ticket agents and airlines will check, but the three Interline agreements (Oneworld, Star Alliance and SkyTeam) are explicitly state-owned airlines must check baggage to the final destination if there is only one ticket (PNR). If your trip includes flights operated by other airlines, your checked baggage is considered “interline baggage.” Hawaiian Airlines is not part of an alliance, but they have Interline agreements with 28 other airlines. Delta does not allow baggage to be refined with other airlines, including other SkyTeam members. It sucks, I know. The interline of your luggage is by far the best way to handle checked baggage on several premium tickets. Without them, you should run into trouble, pick up your luggage, check it again and go through security again. It`s a smooth deal. If only all airlines had interline agreements… I always wondered how it worked and I played with expert flyers when I came across United`s interconnection agreement that looks like this: United has one of the most generous interline interline agreements Interlining (also known as “Interline Ticketing”) is a voluntary commercial agreement between different airlines to treat passengers traveling on routes requiring several airlines. United is by far the most generous U.S. airline in terms of interline.
They have agreements with most Star Alliance airlines, Oneworld carriers and Skyteam airlines, as well as major non-alliances. The only restriction is that you have to pay United fees for luggage, regardless of the class of your second ticket. Choosing to take the airline for your location flight can make the difference between an almost seamless connection or a feeling of already seen, where you have to do the entire airport check-in process again. This means you have to land, go to the baggage locker, pick up your luggage, return to the departure lane, re-check your luggage and return for security. If your international flight departs from a major airport such as JFK, LAX or O`Hare, you must also take a train between the terminals and all your luggage (unless you cannot yet do so at O`Hare). Airlines participating in airline alliances such as Star Alliance, SkyTeam or oneworld almost always have interline agreements. But direct competitors can also benefit from Interline agreements. Interline baggage works the same way, except that you handle passengers who travel with multiple airlines, but you book them baggage. Take, for example, my trip to Australia. We have taken united, Air China, Japan Airlines and Qantas. These are two different alliances and tickets between these four airlines, which means that if there had been no interline of our luggage, we would have had to write the check several times, collect, check the dance several times during this trip. Now, you`re probably going to scratch your head and say why I`d buy two tickets? Well, it`s becoming more and more common as passengers look for ways to reduce costs.
