The country's worst airline for delays has been named, with one firm running an average of 46 minutes behind schedule last year.
Wizz Air - which operates some flights from Edinburgh Airport - took the undesirable top-spot for the second year in a row as the airline with the longest delays in the UK last year.
Data from the Civil Aviation Authority (CAA) was analysed by the PA news agency and found that the Hungarian airline was followed by TUI for delay times.
TUI had an almost as frustrating average delay time of 40 minutes and 18 seconds last year, according to the data.
Meanwhile budget favourites easyJet and Ryanair weren't named amongst the top 10 for delays, with a comparatively respectable 20 minutes and 24 seconds and 22 minutes respectively.
Rory Boland, editor of magazine Which? Travel, said: "These figures are worrying, but will be no surprise to passengers who've had to endure shoddy treatment from airlines for years.
"With a regulator still lacking the appropriate powers to punish airlines who break the law, including withholding refunds, it is difficult to escape the conclusion that some carriers are simply getting away with leaving passengers high and dry."
The CAA has civil powers to take enforcement action against airlines, but court cases can take several years.
Which? has backed proposals to give the regulator more powers, but despite consultation in early 2022 no changes have yet been made.
CAA consumer director Paul Smith said: "The CAA has regularly asked for stronger consumer enforcement powers, including the ability to impose fines on airlines.
"When things do go wrong, we expect airlines to proactively provide passengers with information about their rights when flights are disrupted, as well as offer timely support and assistance.
"We've already raised concerns about Wizz Air and are working closely with the airline to improve outcomes for consumers."
In December 2022, the CAA said it had "significant concerns" about the Hungarian carrier as it was delaying paying refunds and its passengers were far more likely to make escalated complaints than those of other airlines.
Paul Charles, chief executive of travel consultancy The PC Agency, said strong booking levels for flights suggest consumers are "confident that issues have mostly been sorted".
But he warned that airport and Passport Office strikes are "causing disruption and I expect those to worsen in the coming months".
He added: "This may end up an equally difficult and unpredictable year for those expecting smooth journeys on every trip."
Wizz Air did not respond to PA Media’s request for comment.
