A: Each airline has its own rules about transportation of mobility aids. Some will let you take it right to the aircraft door, others require check in. Some will let you check in a mobility device and it won't count against your luggage allocation. It's best to contact the airline in advance and ask what they'll allow and what you should do.
Some airlines allow people to take it straight to the airline door and then the airline staff store it in the 'wheelchair closet' in the cabin. You'll need to pre-arrange this with the airline.
We recommend using the Saljol Travel Bag to help protect the walker from bumps and scratches.
If checking in, some customers simply use the box that it comes in to transport it, which offers extra protection.
Also, most people are fine with travelling with their walker but some airline baggage handlers can be rough on gear, so it's be a good idea to get travel insurance that will cover your walker from damage, and make use of the fragile stickers and tags - these all good things to help in the quest to arrive with your walker intact and ready to roll.
