help! excess baggage options. have been asked to help in finding an option of carting some items overseas instead of the normal route, i.e. paying the airline excess baggage fee apon check-in. THEY want the items, presumably, some suitcases or boxes sent over to the final destination being croatia. i've been told one can have items put directly in the cargo of the same plane or other plane that offers such a service, i guess, for considerably less than paying the excess baggage fee if one were to check-in on the plane they would be boarding. the items would then either be waiting for there arrival at some pick-up point or come shortly after their arrival for them to pick-up. is this true? anyone done this? care to give me some insight? thanks in advance.
