This is the full ranking of airlines based on UK flight punctuality in 2025.
The airlines are ordered from the longest average delay per departing flight to the shortest delay, with the duration in brackets.
The analysis, from Civil Aviation Authority data, took into account all scheduled and chartered departures from UK airports by airlines operating more than 2,500 of these flights in 2025. Cancelled flights were not included.
Rory Boland, the editor of consumer magazine Which? Travel, said that it is “unacceptable” that airline passengers “continue to face unreliable service” amid fare rises.
“Airlines must do more to support travellers during delays, including clearly communicating their rights and eligibility for compensation,” he said.
Mr Boland encouraged travellers to claim compensation from their airline if they believed it was responsible for the delay.
