Tui ranks among worst airlines for UK flight delays

Holiday airline Tui has emerged among the worst performers for flight delays in the UK, as new punctuality data highlights how long waits and disrupted departures remain a stubborn feature of post-pandemic air travel.

New rankings put Tui at the back of the pack

Recent analysis of UK flight punctuality indicates that Tui is among the least reliable major airlines for on-time departures, with performance slipping compared with the years before the pandemic. Consumer research drawing on Civil Aviation Authority departure records between May 2024 and April 2025 places the carrier at or near the bottom of delay league tables for UK-focused airlines.

According to publicly available summaries of that analysis, only around six in ten Tui flights left on time over the 12-month period studied. That represents a clear deterioration from 2019, when roughly two-thirds of the airline’s services departed within the standard 15-minute punctuality window used in official statistics.

Other low-ranked carriers in the same studies include Wizz Air and Ryanair, underlining a broader picture of strain across high-volume leisure airlines. However, Tui’s position near the foot of the table stands out given its focus on packaged holidays, where a single long delay can disrupt entire itineraries for families and tour groups.

Separate industry assessments using different datasets have reached similar conclusions, with some ranking exercises identifying Tui as the least punctual UK airline over the most recent full year of data. While methodologies vary, the overall picture points to consistent challenges in keeping to schedule.

Average wait times highlight persistent post-pandemic strain

The latest figures arrive against a wider backdrop of long-running disruption across UK and European aviation. Official punctuality statistics show that average departure delays, while slightly improved from the worst of the immediate post‑pandemic years, remain significantly higher than in the late 2010s.

Across major UK airports, average delays for departing flights in recent years have frequently hovered in the mid‑teens of minutes, with some hubs recording waits approaching 20 minutes. For passengers on the most affected airlines, including Tui, consumer groups report that average waits can climb considerably higher, particularly during peak holiday periods.

Analysts note that average figures can mask the real impact on travellers. A headline delay of 15 minutes across all flights can coexist with a substantial proportion of services departing more than half an hour late and a notable minority running over an hour behind schedule. For an airline ranking near the bottom of punctuality tables, that pattern translates into a significant risk of missed connections, lost holiday time and added costs on the ground.

Data releases also show that performance varies widely between routes and airports. Some regional bases record relatively strong on-time records for Tui, while sun destinations at the height of summer see far greater punctuality problems. For passengers, that can make planning particularly challenging, with waiting times highly sensitive to both destination and season.

Why Tui and rivals are struggling to keep time

Industry observers point to a mix of structural and operational pressures behind Tui’s poor showing, many of which are shared across the sector. High demand for leisure travel, combined with tight aircraft and crew availability, has left little slack in schedules. When a single flight runs late in the morning, delays can cascade throughout the day.

Air traffic control constraints, especially in congested European airspace, have added a further layer of unpredictability. Airlines that operate dense networks to popular Mediterranean and Canary Island destinations, such as Tui, are heavily exposed to en‑route restrictions, weather diversions and staffing issues in control centres.

Operational experts also point to the complexity of running integrated tour operations, where flights are closely tied to hotel check-in times, transfer services and cruise departures. While that model can deliver value when everything runs to plan, it leaves limited room to reallocate aircraft or crews at short notice without knock-on effects across hundreds of passengers.

Publicly available commentary from travel analysts suggests that some carriers may also have been slower than others to restore spare capacity after the pandemic, choosing to prioritise aircraft utilisation over resilience. In that context, any disruption, from a technical issue to sudden sickness among crew, can push departure times far beyond what passengers experienced before 2020.

How Tui compares with other major airlines

The latest punctuality rankings suggest that Tui’s delays are not an isolated case, but they do stand out relative to several key competitors. Data compiled from CAA records indicates that full-service airlines such as British Airways and some low-cost rivals like Jet2 have generally managed stronger on-time performance over the same period.

While most airlines have seen punctuality worsen compared with 2019, the scale of the decline appears sharper at Tui. Consumer analysis suggests that the gap in on-time performance between the best and worst of the major UK carriers has widened, underlining a growing differentiation in operational reliability just as demand for summer holidays continues to climb.

For passengers choosing between airlines on popular routes, those differences can translate into meaningful variations in average wait times. A family departing from a busy UK airport with a carrier near the top of punctuality tables is, on current trends, more likely to push back close to schedule than one booked on a Tui service from the same terminal.

At the same time, industry comparisons highlight that even stronger-performing airlines are operating in a challenging environment. Sector-wide reports point to elevated rates of late arrivals and departures across Europe, suggesting that while Tui’s position is particularly weak, no major carrier has fully escaped the post-pandemic reliability squeeze.

What longer waits mean for UK holidaymakers

For travellers, the practical consequences of Tui’s poor punctuality are most visible in extended airport waits and disrupted start times for holidays. Longer queues at check-in and security, followed by uncertain boarding times and extended periods sitting on the tarmac, have become familiar complaints in peak season.

Consumer watchdogs advise passengers on all carriers, but especially those flying with airlines that consistently rank poorly for delays, to build additional buffer time into their plans. That includes allowing for later hotel check-ins, flexible transfer arrangements and avoiding tight onward connections on separate tickets.

Regulators and consumer groups continue to remind passengers that they may be entitled to assistance or compensation when long delays occur for reasons considered within an airline’s control, such as technical faults or rota issues. However, passengers often face uncertainty over whether a particular disruption qualifies, and claims processes can be lengthy.

With demand for leisure travel expected to remain strong, aviation analysts suggest that punctuality performance will remain a closely watched metric for airlines competing for UK holidaymakers. For Tui, the latest rankings serve as a renewed warning that persistent delays and higher-than-average wait times risk undermining customer confidence at a moment when travellers have more choice than ever on key routes.
