Be careful what you wish for.
Under a different Regulation (Regulation (EC) No 1107/2006 of the Parliament and of the Council of 5 July 2006 concerning the rights of disabled persons and persons with reduced mobility when travelling by air.) airports are given the responsibility to care for a PRM from their arrival at the airport to the door of the aircraft and vv.
Airlines are mostly unhappy with the costs and, at some airports, with the level of service their customers receive. Meanwhile NGOs representing PRMs are attempting to have the Regulation strengthened. The Regulation allows airports to pass along their costs to the airlines, but these charges are not regulated. Often a monopoly provider charging monopoly rents.
This Regulation came about because some airlines did not view that taking care of PRMs (Passengers with Reduced Mobility) was their responsibility - even though the network airlines for many years had done exactly that. (BTW, does this sound familiar? - drag the LCCs up to the level of network airlines.)
Cryanair also charges for 1107/2006. €0.50/£0.50 per flight - or another €40 million a year (based on their claim of 79.6 m pax per year). They, to my knowledge, have never justified that this fee has any relationship to their actual costs.
