Passengers are being warned to ensure their electronic devices are charged before arriving at the airport, as they could be banned from carrying them on board if they cannot be turned on. This applies to all types of devices, including phones, tablets, laptops, and e-books. The UK Foreign Office states that if a device does not switch on when requested, it will not be allowed on the aircraft. Airport security staff may also ask passengers to demonstrate that their devices are functioning correctly. British Airways has strict safety guidelines in place, stating that electronic items must be charged and turned on before being packed in hand or checked baggage. EasyJet also emphasizes the importance of keeping devices charged, as they may be required to scan boarding passes and batteries may run out during flights. Failure to comply with these regulations could result in passengers being unable to fly.
