There are several items that can be checked in at no additional cost. These items include baby strollers, buggies, prams, wheelchairs and mobility devices**, and crutches or walking frames. As long as each of these items are being used by an infant, toddler, child, elderly, or disabled person who is traveling, they are free of charge.  ** Motorized wheelchairs are permitted, however these will need to be checked in. You must complete a special form 48 hours prior to travel to ensure the airline can accommodate your device.
