This free KLM luggage tag has been around in some shape or form since I started HIF. That's dedication to freebies right there. I wish Delta took lost luggage this seriously. The last time I went to the beach, they lost my bags before sending me a suitcase, which looked nothing like mine, stuffed with women's clothing. Luckily I can pull off a two piece.
You may have to like KLM and then reclick the link above. You should see a page that says “Create your own free personalised luggage tags!” in giant blue letters.
