Am I right in stating that if you come to the airport in a your own wheel chair, no charge is applied. If however you come to the airport without a wheel chair and you request one to be supplied a charge of £18 is applied.
If this is the case surely on most occasions disabled passengers will use their own wheel chair as it will not solely be needed to get to the aircraft but will always be needed to ensure mobility of that person.
While not meaning to be hard here, surely if you do not need a wheel chair for everyday use and expect someone else to provide one, you would expect a payment to be required.
