My mother needs assistance as she has difficulty walking long distances. Is it possible for someone to meet her at the drop-off point with a wheelchair or golf cart? She will also be carrying an oxygen machine, which is the size of a small suitcase (37cm x 37cm x 60cm) and weighs 14 kg. The machine needs to stay upright and be placed in the cabin, not necessarily close to her seat. This is to ensure it remains undamaged during the trip to Inhambane. My father won't be able to handle the machine, so it will need to go on one of the luggage trolleys.

The person assisting at the drop-off will also need to help them through security with the oxygen machine and then again onto the aircraft. My mother has a doctor's letter confirming the necessity of traveling with her oxygen machine.

Please provide me with the cost for assisting her and my father.
