Edinburgh Airport is the worst in the UK for assisting disabled people and the only one to receive a "poor" rating in a new report.

The Civil Aviation Authority (CAA) assessed 30 airports on how well they assisted passengers who have disabilities or reduced mobility.

In July, the airport faced claims an elderly woman was "dumped" at a gate and left there for several hours.

The accessible air travel report laid the blame for the "poor" rating with the airport's previous provider for mobility assistance, which was changed in March.

Glasgow Airport was given a "good" rating by the report, with others in Scotland "taking steps" to improve their performance.

The report said: "Only Edinburgh Airport has performed poorly over the period. This is due principally to the poor performance of the previous assistance provider at the airport, Amey, and a lack of proper oversight by the airport of this performance.

"In March this year, the airport took the decision to terminate the contract with Amey and appointed Omniserv, one of the specialist assistance service providers operating in the UK, as its new supplier."

The report's authors said it welcomed the steps and would continue to monitor the airport.

The CAA's head of consumer enforcement, Matthew Buffey, said: "Our research shows passenger satisfaction with special assistance at UK airports is high with 85% satisfied or very satisfied.

"However, high standards are not always universal, and occasionally things go wrong for disabled people and those with reduced mobility.

"These passengers are very much dependent on airport staff providing the appropriate assistance so it's a really important task for airports to get right.

"We have worked closely with airports to help drive improvements and provide practical guidance where needed.

"Overall we are pleased that performance has generally been good, with some excellent examples of airports supporting their passengers who have mobility needs."

A spokesman for Edinburgh Airport said: "Since the findings of this report were collected six months ago we have - as noted in the report - taken great steps to improve in this area including bringing in OmniServ who won a three-year contract to undertake the provision of services for PRM's (Persons with Reduced Mobility) at Edinburgh Airport.

"Edinburgh Airport is absolutely committed to continuing to improve the passenger experience of everyone who uses the airport, including those with a disability and those with reduced mobility."
