Will be flying to BOM with BA and I would like to take a mobility scooter as a present for my grandad. I'm in F so baggage allowance is not an issue but would need to dismantle the 35-40 kg scooter and pack securely to check in. Is there any scope for checking it in fully assembled? I assume actually disabled passengers are allowed to gatecheck (?) but I don't particularly fancy driving around the airport in it, although it would be amusing! Will the battery be an issue?
