The report rates 14 airports as "good" and 11 as "very good", with Heathrow, Edinburgh and Prestwick "needing improvement". Nearly 2% of passengers – 5.5 million – requested assistance at UK airports last year.
The CAA said: “With more people travelling through our airports, and more of these people requesting assistance services than ever before, the latest report from the regulator shows that the majority of airports rated positively, but three airports need improvement.”
