If you are taking your own wheelchair with you, you must report it in advance to the airline while indicating its measurements (height, width, and weight).
Important: If you are traveling with a battery-powered wheelchair, when booking your flight please also provide information about the type of battery used.
Gel and dry-cell batteries may remain in the wheelchair and require no special preparations for transport. However, before checking it you must secure and disconnect the batteries and isolate their poles.
For security reasons, wheelchairs with wet-cell batteries must be specially packed. Please contact your airline in advance for details.
