Most airlines will allow you to push your child in his or her Bugaboo stroller to the gate. There, you can fold it into its most compact and easy-to-handle size. The airline staff will place the stroller in the general luggage compartment of the plane and will deliver it to you as you exit the plane at the end of your flight. Please contact your airline for specific information. If you need to know the folded size of the stroller, please visit the compare page. Bugaboo recommends using a transport bag for extra protection and checking in the stroller as odd size luggage. This minimizes the chance of damage to your Bugaboo stroller. Check here for information on the Bugaboo transport bag. Your warranty is not valid for damage sustained during air travel, with or without the transport bag.
