TUI ranked among UK’s worst airlines for flight delays

Fresh data highlights worsening punctuality

Recent reviews of UK Civil Aviation Authority (CAA) departure data show that TUI has consistently ranked near the bottom of the tables for on-time performance, with average delays running into the tens of minutes per flight. Consumer-facing analyses of the year to April 2025, as well as separate assessments focused on 2024 operations, have repeatedly identified the airline as one of the least punctual major carriers operating from UK airports.

In one widely cited comparison of six of the country’s largest airlines, TUI recorded the lowest proportion of on-time departures, with fewer than six in ten flights leaving within the industry’s standard punctuality window. Other major UK and European airlines also saw timeliness deteriorate compared with pre-pandemic performance, but TUI’s figures placed it at the back of the group.

Separate rankings drawing on CAA data for 2024 and early 2025 similarly place TUI among the worst performers for both departure and arrival punctuality. In some periods, only a little over half of its flights were reported as operating on schedule, with average delays exceeding 20 minutes, reinforcing its reputation as one of the sector’s least reliable options for UK-based travellers.

While precise rankings fluctuate between different time frames and methodologies, the overall picture is that TUI’s punctuality has slipped significantly from 2019 levels and now compares unfavourably with many rivals, including several low-cost carriers.

Impact on holidaymakers and tour customers

TUI holds a distinctive position in the UK market as a tour operator airline carrying large volumes of package holiday customers to Mediterranean resorts, the Canary Islands and long-haul leisure destinations. For many travellers, a TUI flight is directly tied to a once-a-year family holiday, intensifying the frustration when significant delays disrupt departure and arrival plans.

Long waits at departure airports can quickly cascade into missed hotel check-in times, rearranged transfers and lost time at resorts. For flights to long-haul destinations, late arrivals may also interfere with onward travel, cruise departures or pre-booked excursions. Travel blogs and passenger forums over the past year have carried a steady stream of complaints about extended hold-ups on popular leisure routes, adding anecdotal weight to the official punctuality figures.

Delays also raise questions around accommodation and care for passengers. Publicly available information from TUI indicates that the level of support provided varies according to the length of any disruption, but consumer groups continue to encourage travellers to familiarise themselves with their rights under UK and EU regulations in case overnight stays or substantial rescheduling becomes necessary.

For families travelling with young children, older passengers or those with reduced mobility, repeated schedule changes and late-night departures can be particularly challenging. As a result, punctuality metrics are increasingly influencing how UK holidaymakers choose between carriers when booking through travel agents or comparison platforms.

Industry-wide pressures but mixed performance

The deterioration in TUI’s on-time performance comes against a backdrop of broader strain across European aviation. Staffing shortages, air traffic control capacity issues, industrial action and bouts of severe weather have all contributed to rising delay levels since travel demand rebounded after the pandemic.

Across major UK airlines, analyses of the year to spring 2025 show that none have fully restored the punctuality seen in 2019. However, while many carriers are facing similar headwinds, their relative performance differs, and TUI’s results place it among the least reliable of the large UK-based operators.

Industry commentators note that leisure-focused airlines can face particular challenges when disruptions coincide with peak holiday travel, as they often operate highly seasonal schedules with intense utilisation of aircraft and crews. Any technical issue or air traffic restriction can therefore have knock-on effects across multiple rotations in a single day.

At the same time, comparisons with airlines that have maintained stronger punctuality despite the same external pressures suggest that operational choices, fleet resilience and contingency planning also play a significant role. Analysts point to the scale of spare aircraft, crew rostering flexibility and investment in real-time operations control as factors that can help limit the length and frequency of delays.

What passengers can expect when flights run late

Under UK and retained EU regulations, notably UK 261, travellers departing from the UK or EU may be entitled to compensation when their flights suffer long delays, provided the disruption is not caused by what regulators term extraordinary circumstances such as severe weather or certain air traffic control restrictions. The level of compensation depends on the length of the delay and the distance of the flight.

Consumer advocates report that, as delays have become more common across the industry, claims volumes have risen, with UK passengers collectively recouping significant sums in compensation over the past two years. TUI, as one of the country’s largest leisure airlines and a frequent presence in delay rankings, features prominently in this landscape.

Published guidance from the airline specifies that in cases of extended disruption, customers may receive food and drink vouchers, hotel accommodation where necessary and assistance with rebooking on alternative services. However, passengers are often advised by independent consumer bodies to keep all receipts, document timings carefully and check whether the reason given for the delay would qualify for monetary compensation.

For travellers concerned about punctuality, experts commonly recommend opting for earlier departures where possible, allowing extra time for connections and avoiding tight same-day plans such as weddings or cruise departures on the day of arrival. Some travel advisors also suggest considering travel insurance products that offer specific coverage for long delays alongside standard medical and baggage protections.

How TUI compares with rivals and what comes next

Despite its current difficulties with on-time performance, TUI remains one of the UK’s largest airlines by passenger numbers, with a significant presence at regional airports as well as major hubs. Its extensive route network to holiday destinations, bundled with hotel and transfer packages, continues to attract customers seeking a single-brand travel experience.

Comparative data indicates that other airlines, including some low-cost carriers, have outperformed TUI on punctuality metrics while operating similar or higher numbers of flights. In rankings focused on UK departures, rival carriers have recorded lower average delays and higher proportions of on-time services, suggesting there is scope for TUI to narrow the gap through operational improvements.

Industry reports indicate that airlines across Europe are investing in measures designed to stabilise schedules for the upcoming peak seasons, from recruiting additional crew to securing more spare aircraft and refining maintenance planning. Market-watchers will be assessing whether TUI’s delay statistics begin to improve in future CAA releases as these initiatives take effect.

For now, TUI’s repeated appearance near the bottom of UK delay rankings is likely to remain a talking point for travel agents and customers alike. With passenger demand forecast to remain strong, the airline’s ability to restore punctuality closer to pre-pandemic levels may prove critical in shaping perceptions of its value and reliability in a crowded leisure travel market.
