As the UK enters its busiest period for air travel, with 550,000 passengers expected to fly this Friday alone, the UK Civil Aviation Authority is urging travellers to review how they pack their electronic devices. Incorrectly stored lithium batteries in checked luggage are increasingly triggering flight delays, emergency diversions, and safety incidents.

Why Lithium Batteries Pose a Flight Risk

Lithium-ion batteries—found in smartphones, laptops, and power banks—are essential for modern travel, but they carry inherent risks if damaged or poorly manufactured. When these items are stowed in the aircraft hold, they are inaccessible to cabin crew. If a battery begins to overheat or catch fire, the inability to intervene quickly can force a flight to be rerouted or evacuated.

Reports of overheating or malfunctioning passenger devices have nearly doubled between 2024 and 2025. With passengers now carrying an average of four rechargeable devices each, the risk of a thermal runaway event in the cargo hold has become a significant operational concern for airlines.

Devices That Must Stay in Your Cabin Bag

To ensure your flight departs on time and remains safe, the following items must never be placed in checked-in luggage. These should be kept in your hand luggage so they can be monitored throughout the journey:

Power banks: The most common cause of concern; limit to two per person.
Vapes and E-cigarettes: Must be kept in the cabin to prevent accidental activation.
Spare lithium batteries: Including loose batteries for cameras or tools.
Bluetooth speakers and Wireless headphones: Often contain high-energy density batteries.
Electric fans and Fitness watches: Frequently overlooked items.
Laptops, Tablets, and E-readers: Should be easily accessible during the flight.

Pre-Flight Safety Checklist

Before heading to the airport, a few minutes of preparation can prevent your bag from being offloaded or your flight from being delayed:

Inspect your gear: Check your power banks and devices for signs of damage. If a battery is bulging, swelling, or shows signs of overheating, do not take it on the plane. Dispose of it safely at a local recycling centre.
Verify your gear: Stick to reputable high street retailers when purchasing chargers. Cheap, non-compliant power banks are significantly more likely to malfunction.
Respect the limit: Most airlines restrict passengers to a maximum of two power banks. Always check your specific airline’s policy before arriving at the terminal.
Never charge onboard: While your devices must be in the cabin, they should not be recharged using the aircraft’s power supply unless explicitly permitted by the airline, as this increases the risk of overheating.

By ensuring these items are packed correctly, passengers play a direct role in reducing the risk of fire incidents and avoiding the disruptive flight delays that have plagued recent summer schedules.
