Certain batteries are considered Dangerous Goods and regulated by IATA. Don’t see how his suit stands a chance.
So what batteries can be on a plane and what can not be? I know some people in a motorized wheelchair do fly.
Yeah, if they are consistent in denying the batteries, it sounds like the flyer just didn’t do his research.
He should have brought a non-powered wheelchair.
Or they could buy one at Walgreens for $79. If they can afford to fly, they can afford to buy a wheelchair. Probably could rent one somewhere much cheaper.
Depending on how often the airline runs into this, the airline should keep some wheelchairs on hand and rent them out. Or arrange a rental at the flyer’s destination.
Did he get the $2000 battery back after his return flight?
Because he had obtained the necessary permission to have them in his carry on luggage. Which is what the IATA rules called for.
