Heathrow is under fire for failing in the service it gives to thousands of disabled passengers who use the airport every year.
It has been rated among the worst airports in the UK for disabled passengers and told it must improve.
A survey by the Civil Aviation Authority of thirty airports rated it in the bottom four with a "poor" rating. The regulator said the airport had "fallen short of expectations."
Gatwick and Southampton were rated good but failed to get into the very good catogory.
“UK aviation should be proud that it continues to serve a rapid increase in the number of passengers with a disability.
Our surveys, along with the airports’ own studies, have shown high levels of satisfaction among disabled passengers and we have seen some examples of excellent service where assistance is well organised and delays are minimal. However, East Midlands, Exeter, Heathrow and Manchester have fallen short of our expectations and we have secured commitments from them to make improvements. We will monitor their implementation over the coming months to make sure that services for passengers with a disability or reduced mobility continue to improve.”
