East Midlands Airport has been ranked one of the worst airports in the country for the help it provides for disabled passengers.
A new report has dubbed the airport "poor" for its assistance in aiding disabled travellers.
The airport, near Castle Donington, was just one of four rated poor, while the majority in the UK were rated as good.
The other three airports which have fallen into the lowest rating are Exeter, London Heathrow and Manchester.
The Civil Aviation Authority's Richard Moriarty said: "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 airport's 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."
To be rated as poor, the airport must have failed in one or more of the following areas:
How long passengers have to wait for assistance - both departure and arrival.
The level of passenger satisfaction with the assistance provided, gathered from CAA passenger surveys and airports' own surveys.
How much consultation airports had with disability organisations regarding assistance services, what consultation methods were used, if issues were addressed and what, if any, action was taken.
Speaking with sister title, the Leicester Mercury, an East Midlands Airport spokesman said: "For several months we have been working with disability groups and the CAA in order to ensure that we significantly improve the service we are able to offer our passengers who have restricted mobility.
"Our highest priority is to ensure that every one of the millions of passengers who use our airport each year experiences the same level of excellent service.
"We have recently invested in new equipment that enables passengers with restricted mobility to more easily board aircrafts and introduced a number of customer improvement initiatives across the airport.
"We will continue to work closely with disability groups and independent specialist consultants to deliver a significant improvement in this area."
