Wizz Air, named as the worst airline in the UK for flight delays for the past two years, has said passengers should trust it this summer. The company’s UK managing director, Marion Geoffroy, said the airline has reviewed “every single aspect of its operations” to boost resilience and has performed well in recent months. Analysis of Civil Aviation Authority data shows Wizz Air’s departures from the UK last year were delayed by more than 46 minutes on average, longer than any other airline. It also ranked last in 2021. Consumer magazine <i>Which?</i> pointed to a dismal record on “cancellations, delays” and even basic levels of <a href="https://www.thenationalnews.com/travel/2023/07/13/airport-drop-off-fees-charges-increase-at-more-than-a-third-of-airports/" target="_blank">customer service</a> from the Hungarian airline. But on Saturday, Ms Geoffroy said “passengers should trust Wizz and they should book with Wizz”. “We don’t see any area except for air traffic control [ATC] where I would have concerns,” she added. “Of course, we might face some strike actions at certain airports but in terms of our operations – what we control – we’ve put a lot of strength in the entire system.” Wizz Air operates flights from eight UK airports including Birmingham, Edinburgh, Gatwick and Luton. The company has overhauled flight schedules, rostering and the availability of spare aircraft parts since 2022. In December 2022, the CAA said it had “significant concerns” about Wizz Air as it was delaying paying refunds for cancelled flights, and its passengers were far more likely to make escalated complaints than those of other airlines. “We do apologise. We don’t want this to happen again,” Ms Geoffroy said. She said that by operating flights as early and late in the day as possible, the airline has been able to introduce “extra buffers” involving aircraft being scheduled to remain on the ground for part of the afternoon, limiting the knock-on effect of morning delays. More staff are working on two flights per shift rather than four, reducing the likelihood of disruption, meaning labour laws prevent them from completing the final flight, forcing it to be cancelled. Wizz Air has made more spare aircraft engines and other parts available this summer to cut the impact of faults. Ms Geoffroy said the airline has also worked with airports and ground-handling companies to ensure there is no repeat of the staffing shortages that caused much of the chaos during last year’s surge in demand for air travel. She said airline managers have “tested ourselves already” during peak periods this year over Easter, bank holiday weekends and half-term school holidays. “It’s gone well,” she said. “We were mostly affected by external factors such as ATC strikes or weather. They were the main reasons for disruption so far. “We know we’re going to face them in July and August because the ATC situation is not going to be solved this summer. “But we’ve seen that these buffers we’ve put in place have helped us overcome disruption due to external factors. “We’re very happy with April, May and June. The number of flights we cancelled was the lowest in the industry compared to our peers.” For <i>Which?,</i> the optimistic vision from Wizz Air needs to be followed up on the ground. “Wizz Air was named the worst short-haul airline in our recent survey, and its dismal record on cancellations, delays and meeting even basic standards of customer service mean it should be avoided at all costs,” said Rory Boland, editor at <i>Which? Travel.</i> “Passengers have been expected to sit back and put their trust in airlines like Wizz Air for far too long, only to be repaid with having their travel plans ruined and their rights disregarded. “It’s time for Number 10 to finally show it is on the side of consumers and legislate to give the aviation regulator fining powers, so it has the teeth to take airlines to task.” It emerged this week that Gatwick is suffering more flight delays due to ATC limits than any other major European airport. EasyJet cancelled 1,700 summer flights – mostly from Gatwick – in response to “unprecedented” ATC restrictions. Gatwick airport staff are also poised to trigger weeks of misery for travellers through England's second major international hub after announcing a series of strikes in an unresolved pay dispute. The walkout will involve 1,000 workers at Gatwick, including baggage handlers, check-in staff, ground handlers and other key personnel, who will stage eight days of strikes spread across the peak summer travel period. The union Unite declared that the strike actions will take place from July 28 to August 1, and then from August 4 to August 8, given the failed negotiations with the four major ground-handling companies: ASC, Menzies Aviation, GGS and DHL Services.
