Get your free customized luggage tags from KLM Airlines, and enter their contest to win a free pair of tickets (look for the "Design your own free luggage tags" box on the bottom left).
About the contest entry - it is laborious and a several step process which involves downloading pictures from their website and posting things. I ended up not entering, so no free tickets for me. But the luggage tags? Hopefully on their way in the next 3 weeks.
Thanks to Lydie and Inflightout for the alert on this.
