What assistance are disabled passengers entitled to when travelling?
A legally enforceable right to free assistance through the airport and onto the aircraft, plus obligations on airlines around equipment and refusal — and the rights are considerably stronger than most travellers realise, though delivery frequently falls short.
What you are entitled to at the airport, under assistance regulations:
Help from a designated arrival point — car park, station, drop-off — through check-in, security and to the gate.
Boarding and disembarking assistance, including transfer to and from the seat.
Help with baggage.
Assistance on connections, and to the exit on arrival.
All of it free of charge. Airports fund it through a charge levied on airlines, not on you.
What airlines must do:
Carry mobility equipment free, in addition to the baggage allowance — wheelchairs, walking aids and medical equipment do not count toward your limit.
Carry a recognised assistance dog, subject to entry rules for the destination.
Not refuse booking or boarding on grounds of disability, except where required to meet safety requirements or where the aircraft size makes it physically impossible. Where they refuse, they must offer alternatives and explain.
Accommodate a companion where one is required for safety reasons.
What you have to do:
Request assistance in advance — at least 48 hours before departure, which is the condition that most often causes problems when missed. Assistance should still be provided without notice, but cannot be guaranteed.
Provide detail, since "wheelchair assistance" covers several very different needs — the codes used distinguish whether you can walk, manage stairs, or move to a seat.
Declare battery types for powered wheelchairs, since lithium batteries have specific rules.
Arrive by the stated time.
Where it goes wrong: damaged wheelchairs, long waits for assistance on arrival — including passengers left on aircraft — and equipment separated from passengers. Damage to mobility equipment is subject to liability limits in international carriage, which has been widely criticised as inadequate.
Complain to the airline, then the national enforcement body.
