My boyfriend and I are going to take the flight Lima (Peru) - Madrid (Spain) (1 hour layover) - London Heathrow (3 hours layover) - Stockholm Sweden. Our booking was made through Iberia and the whole trip has already been set; in Heathrow we will fly with British Airways but with an Iberia flying code.
However, my boyfriend will only be flying to Madrid because he has to stay there for one day and then he'll come to Sweden the next day with another new flight.
Since he has to catch the train in Madrid fast after landing we prefer that his luggage goes all the way to Stockholm Sweden with me so I can take it home with me. But we are afraid that once they realize that he is not on board from Madrid-London-Stockholm that they will take out his luggage in London and keep it there.
Does anybody know how it works? I've called Iberia and they only say you will have to see at the airport which is not helpful at all. Does someone know or has any experience?
