Tui named among worst airlines for UK flight delays

Tui has been ranked among the worst airlines for UK flight delays in the latest analysis of Civil Aviation Authority data, intensifying scrutiny of punctuality across the leisure travel sector as millions of holidaymakers prepare to fly this summer.

Fresh data highlights scale of UK flight disruption

Newly compiled figures from recent UK Civil Aviation Authority departure records show that Tui sits near the bottom of the table for on time performance from UK airports, with average delays on many routes stretching beyond 20 minutes. On one high profile leisure route between Birmingham and the Greek island of Zakynthos, separate analysis of 2025 operations identified an average delay of around 46 minutes, placing it among the worst performing UK departures.

The latest rankings compare 34 airlines that each operated more than 2,500 flights from UK airports over the assessment period. Within that group, Tui is reported to be among a cluster of carriers with some of the longest average departure delays, alongside airlines such as Air India, Wizz Air, Jet2 and Ryanair on certain routes. Although the precise position can vary slightly between studies and timeframes, Tui is consistently identified as one of the least punctual major UK operators.

Consumer research published by organisations such as Which? has previously flagged similar concerns. A review of performance between May 2024 and April 2025 found that Tui had the lowest proportion of flights leaving within 15 minutes of schedule among the six largest UK airlines, suggesting that punctuality problems are not confined to isolated routes or a single season.

Industry analysts note that while average delays of 20 to 25 minutes may appear modest compared with severe disruption, they can quickly compound across busy summer timetables. Late arriving aircraft often lead to subsequent knock on delays, while even relatively short waits can cause missed rail connections, lost hotel check in windows and additional childcare or parking costs for travellers.

Holiday routes and regional hubs hit hardest

The data indicates that some of the longest average delays for Tui are recorded on classic leisure routes from regional UK airports to Mediterranean and long haul sun destinations. Services from Birmingham, Manchester and other large holiday gateways to Greek islands, the Canary Islands and Mexico feature prominently among those with prolonged waits at departure.

These routes tend to be highly seasonal, with aircraft operating packed schedules on peak travel days. Aviation consultants say that when aircraft are scheduled tightly around popular mid morning and early afternoon departure waves, there is limited slack in the system if an earlier sector runs late, if baggage loading takes longer than planned, or if passengers are held at security and boarding is delayed.

The concentration of delays on leisure focused services also means that disruption can have disproportionate consequences for travellers. Package holidays typically bundle flights with fixed hotel stays, cruise departures or onward transfers. When flights leave late or arrive after midnight, families can lose a portion of their first day, face additional transfer charges, or be forced to rebook missed activities at their own expense.

Separate analyses of UK airport punctuality show that some of Tui’s key bases have themselves been under pressure. Manchester and Birmingham airports have recently appeared among the worst ranked UK hubs for average departure delays, highlighting how airline and airport performance are closely intertwined when it comes to keeping flights running to schedule.

Airline and industry responses to delay concerns

Publicly available statements from airlines and trade bodies stress that delays can stem from a mix of factors within and beyond carriers’ direct control. They point to air traffic control restrictions, adverse weather, staffing shortages across ground handling and security, and industrial action in different parts of Europe as recurring sources of disruption that affect multiple operators simultaneously.

Carriers including Tui also highlight their overall flight completion rates, arguing that the vast majority of scheduled services do eventually operate, even when departure times slip. Industry data cited in recent coverage suggests that completion rates for major leisure airlines remain close to 99 percent in the UK, meaning outright cancellations are still relatively rare compared with the number of delayed flights.

At the same time, consumer advocates contend that airlines need to build greater resilience into schedules and improve communication when things go wrong. Reports indicate that passengers frequently complain about sparse updates at the gate, limited information about the underlying cause of disruption and difficulties securing overnight accommodation or rebooking when delays stretch into many hours.

Regulators have urged airlines and airports to learn lessons from successive summers of disruption and to invest in staffing, contingency planning and better use of data to predict pinch points. Industry observers will be watching whether the latest poor punctuality rankings prompt tangible operational changes from those carriers repeatedly appearing at the bottom of delay tables.

What delays mean for passenger rights and compensation

Under longstanding UK and EU air passenger protection rules, travellers on flights departing from the UK or on services into the UK operated by a UK or EU carrier may be entitled to compensation when they face long delays that are deemed to be within the airline’s control. Payouts are linked to the length of the delay and the distance of the flight, with potential compensation on some routes reaching several hundred pounds per person.

Data published by compensation specialists indicates that UK travellers have claimed billions of pounds in disruption related payments over the past two years, with airlines that appear frequently in delay rankings facing sustained volumes of claims. Leisure carriers with a high proportion of holiday traffic are particularly exposed, given that delays often involve family groups travelling together, which can multiply the sums involved.

However, not every delay qualifies. Airlines can decline to pay when they classify the disruption as arising from extraordinary circumstances such as severe weather, sudden airspace closures or certain kinds of air traffic control failures. Disputes over whether a delay was within an airline’s control are common, and some passengers report having claims rejected several times before turning to independent adjudication or specialist firms.

Consumer organisations advise travellers to keep detailed records when a flight is delayed, including boarding passes, receipts for food, transport and accommodation, and any written updates received from the airline. These documents can be crucial when submitting a claim weeks later, particularly if the carrier contests the cause or length of the delay.

How UK travellers can plan around delay risk

The latest rankings placing Tui among the worst airlines for UK flight delays are expected to influence how some travellers plan their holidays, even if price and schedule still dominate booking decisions. Travel agents and comparison tools increasingly highlight historic punctuality alongside fares, giving passengers more information about potential disruption risk when choosing between airlines and routes.

Specialist travel advisers suggest that those flying with carriers that have struggled with punctuality build extra time into itineraries, particularly when connecting to cruises, long distance rail services or separate onward flights that are not part of a single booking. Allowing generous connection windows, avoiding the last departure of the day on critical routes and travelling a day earlier for major events can all reduce the impact if a delay occurs.

Passengers are also encouraged to check in advance what support their airline and travel insurer provide during disruption. Some policies offer additional cover for long delays, while certain package holidays may include stronger protections than flight only tickets. Understanding these terms before departure can help travellers make faster decisions about whether to accept rebooking options, arrange their own accommodation or pursue compensation later.

As the peak summer season approaches, attention will focus on whether punctuality across UK airlines improves compared with previous years. With Tui now firmly associated with some of the country’s worst delay statistics, its performance in the coming months is likely to be closely scrutinised by regulators, consumer groups and passengers alike.
