Frustrated airline passengers across the UK could be owed significant cash payouts as new data reveals a dramatic surge in complaints and millions of pounds in unclaimed compensation. The findings emerge as holidaymakers begin planning their 2026 travel, with experts warning that many travellers remain unaware of their rights when flights encounter problems.
Complaints Skyrocket by 33% Annually Since 2021
Passenger grievances submitted to the Civil Aviation Authority have jumped by an average of 33% each year between 2021 and 2024, highlighting growing dissatisfaction with how airlines handle disruptions. In total, a staggering 18,397 complaints were lodged with the aviation regulator between January 2021 and July 2025, covering issues ranging from delayed compensation payments to last-minute cancellations.
During this period, airlines have paid out more than £5.3 million in compensation through the CAA process alone, with individual annual payouts sometimes exceeding £1 million. Despite these substantial figures, millions more in compensation remains unclaimed due to passenger confusion and airline opacity.
Jet2 Tops Complaint League Despite Industry Awards
The airline attracting the highest number of complaints was Jet2, with 2,467 cases raised over the surveyed period. This notable figure comes despite the carrier recently being crowned Best Airline at the 2025 Routes Europe Awards for the second consecutive year.
Qatar Airways followed with 1,581 complaints, while low-cost operators featured prominently in the complaint rankings. Ryanair logged 738 complaints, with other major carriers including Vueling, Norse Atlantic Airways, and Aer Lingus also recording significant complaint numbers.

Why Millions in Compensation Goes Unclaimed
A comprehensive survey of 2,000 UK adults who have travelled by plane reveals why substantial compensation amounts remain unclaimed. One in three travellers (33%) abandoned their claim or failed to pursue it because they were unaware they were entitled to compensation. Meanwhile, one in five (20%) cited the process as too stressful to navigate.
Even among those who attempted to claim, more than one in four (28%) found the process overly complicated. Alarmingly, fewer than half (44%) reported being informed by their airline that they might be eligible for compensation, and two in five (41%) believe airlines should demonstrate greater transparency regarding their policies.
Adding to passenger concerns, one in four travellers (25%) suspect airlines deliberately delay claims to discourage passengers from pursuing them. Alvaro Iturmendi, travel insurance expert at Confused.com, commented: "Flight disruption remains one of the biggest frustrations for passengers. The thousands of unresolved cases demonstrate how many holidaymakers are left without closure and often out of pocket. For affected travellers, claiming compensation can feel confusing and drawn-out, exacerbating the stress and financial strain of disrupted travel plans."
Understanding Your Passenger Rights
Passengers flying from the UK or EU are protected under EU Regulation 261/2004, which establishes strict compensation rules. Mr Iturmendi emphasised: "It's crucial for people to understand their rights before flying. If your flight is delayed or cancelled, you may be owed compensation, but many passengers don't know where to begin. Understanding what you can claim and how to approach your airline can make a significant difference."
Key Compensation Rights Include:
- Delays exceeding 3 hours: Compensation varies by distance:
- €250 (approximately £220) for flights up to 1,500km
- €400 (approximately £350) for flights between 1,500–3,500km
- €600 (approximately £520) for flights over 3,500km
- Cancellations: If cancelled less than 14 days before departure, passengers are entitled to a refund or re-routing and may qualify for additional compensation.
- Food, drink and accommodation: Airlines must provide meals, refreshments, and hotel accommodation for overnight delays, including necessary transport.
When airlines reject claims, the CAA can intervene, review cases, and challenge airlines on passengers' behalf if compensation appears to have been wrongly refused. To address widespread confusion, Confused.com has launched an airline delay compensation calculator, allowing passengers to check potential entitlements by entering their flight number—a move designed to prevent airlines benefiting from passenger confusion and inertia.
