We flew to Florida this week- despite my husband's concerns about the plane, taking his power wheelchair, etc. it was actually quite comical. He was in a line of 18 people in transport chairs! It was like a mass exodus of old people to the land of sunshine and warmth! Anyhow, the facilities supervisor personally met with us (I had called ahead!) and went over how to properly turn things off. (My original call to the airlines had them telling me The manual said they would take the battery out, store it in a wooden box, etc.). Anyhow, I took documentation and instructions from our PERMOBIL rep so we could instruct the supervisor on simply turning off a fuse. He was very helpful and allayed hubby's fears. The flight was great and we are now enjoying surf and sand in 70+ temperatures! So relieved it all worked out and hubby has his chair for more freedom.
