I tend to bring something quite fragile with me as cabin luggage. On my next journey I want to bring a special bottle of champagne (because of sentimental reasons). Unfortunately you can't bring a bottle with you as cabin luggage.
I already know that it is okay to bring a bottle of champagne as check-in luggage (even confirmed by the airline (Dutch).) I am wondering how you can transport a bottle of champagne in your luggage in such a way it doesn't break easily.
