Power banks are an everyday travel item, but where passengers pack them matters. On 22 July 2026, the UK Civil Aviation Authority (CAA) warned that incorrectly packed lithium batteries can create serious safety risks and contribute to delays, diversions and other disruption during the busy summer travel period.
The warning is useful well beyond UK domestic travel. Passengers flying internationally—including between the UK and Türkiye—should understand both the battery-safety rules and the separate passenger-rights questions that can arise if a flight is delayed, cancelled or diverted.
Why did the CAA issue a lithium-battery warning?
The CAA said summer 2026 incidents had already included flight diversions and smoking checked baggage involving incorrectly packed lithium batteries. It also reported that UK reports involving overheating or malfunctioning passenger devices nearly doubled between 2024 and 2025.
Power banks are particularly relevant. The regulator’s passenger research found that 49% of respondents travel with a power bank, while more than a third were unaware of the dangers associated with placing lithium batteries in checked baggage.
The practical message is straightforward: check the current rules for your device, airline and journey before travelling. Power banks and spare lithium batteries generally belong in cabin baggage rather than checked baggage, subject to applicable capacity limits and airline requirements.
Why can one battery affect an entire flight?
Lithium-battery rules are safety requirements, not simply baggage formalities. A damaged, overheating or incorrectly packed battery can require intervention before departure. A serious incident can also contribute to a diversion after an aircraft has departed.
That means a problem involving one passenger’s baggage can potentially disrupt many journeys. But identifying the immediate cause is only the beginning of the passenger-rights analysis.
If a battery incident disrupts your flight, are you entitled to compensation?
Not automatically. Flight disruption can create several different rights, and they should not be treated as interchangeable.
Depending on the journey, circumstances and applicable law, passengers may have rights concerning care and assistance during a long delay, rerouting or a refund after cancellation, reimbursement of reasonable expenses in some circumstances, and fixed financial compensation where the legal conditions are met.
Whether fixed compensation is payable can depend on the actual cause of the disruption and whether the circumstances were within the airline’s control. A safety incident involving a passenger’s lithium battery can therefore raise a different compensation question from an airline operational problem.
That does not necessarily mean every other passenger right disappears. For journeys covered by UK rules, Airdelay’s UK261 compensation guide explains compensation, care, refunds and rerouting, while the refund versus compensation guide explains why those remedies should be considered separately.
What about flights between the UK and Türkiye?
UK–Türkiye journeys show why passengers should not decide their rights from the destination or airline name alone.
A flight departing from the UK can fall within UK261 regardless of whether the operating airline is a UK carrier. The analysis can differ in the opposite direction: for a flight departing Türkiye for the UK, the identity of the operating carrier matters when assessing whether UK261 applies. Other passenger-rights frameworks may also need to be considered depending on the itinerary and circumstances.
Airdelay’s UK–Türkiye flights and UK261 guide covers that route-specific question. The broader UK261, EU261 and Turkish passenger-rights comparison explains why similar disruption can produce different legal outcomes on different journeys.
And if you are flying with AJet?
The same principle applies to AJet passengers: the airline’s nationality alone does not determine the passenger-rights framework.
For example, an AJet flight departing the UK can be within UK261’s scope even though AJet is not a UK airline. The analysis can differ for an AJet-operated flight from Türkiye to the UK.
Passengers dealing specifically with an AJet delay or cancellation can use Airdelay’s AJet compensation claim guide for airline-specific route and passenger-rights context. A lithium-battery safety incident does not, by itself, mean a particular passenger automatically qualifies for fixed compensation; the cause and circumstances still matter.
What should you do if your flight is disrupted?
Follow airline and airport safety instructions first. If disruption occurs, keep any information the airline provides about its cause, along with your booking confirmation, boarding pass or other travel documents and relevant airline messages.
If you have to pay reasonable costs for meals, accommodation or transport because required assistance is not provided, retain itemised receipts. If your flight is cancelled, understand the difference between rerouting and accepting a refund before choosing an option.
Most importantly, do not assume that a safety issue means the airline has no further obligations. Fixed compensation is only one part of passenger-rights law.
Battery awareness matters during the 2026 summer travel season
The CAA’s warning comes during one of aviation’s busiest periods, when millions of travellers are carrying phones, laptops, tablets and power banks. Correct battery packing is both a safety measure and a practical way to reduce avoidable disruption.
For passengers, the lesson has two parts: pack lithium batteries correctly before reaching the airport, and if a flight is nevertheless delayed, cancelled or diverted, identify the actual cause and the passenger-rights framework covering the journey before deciding what remedies may apply.
This article provides general passenger-rights information. Eligibility for compensation or other remedies depends on the individual journey and circumstances of the disruption.
