If you are travelling and have to change airplane on your way, tell the staff where you do your check-in, to check-in the luggage all the way to the end-destination. Some will say this is not possible but it is! You just need to show your ticket to the other flight when you do the check-in in Sweden.

We did that when we travel´d to Koh Samui from Gothenburg (with stop ang change of airplane in Bkk) and it worked! Our friends, who not did this, had to check-out and then check-in their luggage again in Bangkok. We who had done this already in Sweden cold just relax, eat some food and wait for the next flight =)
