For example, for my customers who travel in British Airways first class and have a separate Alaska ticket to the international city Gateway, they don`t have to pay an Alaska Airlines baggage fee for their positioning flight. Be sure to bring a printed copy of your entire flight ticket, including PNR and ticket number, so that the check-in officer can properly mark your baggage at their final destination. Remember that when you return to the United States, you must always collect your luggage in the first American city where you arrive and therefore clear customs and then drop off your luggage again. So make sure you have enough time to do this if you have a U.S. connection on a return flight, as you can`t drop off luggage. * A single ticket also means a connective (i.e. conjunctive) ticket. Conjugated tickets are sequential in number on the same ticket stock. It is not possible to make the tickets of different airlines too connective. . . .
