Yes. You you can buy a cardboard bike box at certain airports. We recommend researching the specific airport prior to travel to find if anyone has them available for purchase. Check out our French Airport pages for more information. Sometimes a dedicated provider such as Swissport will have them available for sale. At other times it will be the major airline provider at that particular airport. You may also be able to purchase these from left luggage. With some forward planning you may find the nearest local bike store will also have these available for you to collect.
