Brand new security measures are expected to cause long delays for passengers flying to the USA from many countries including the UK. The general advice is quite simple but very important: MAKE SURE your laptop and iPhones etc are fully charged so they can be turned on to prove they are not hidden bombs
Passengers that ignore this advice will have their gadgets taken from them. In some cases, they will also be refused travel entirely by the airline. This is all due to new intelligence that some groups have devised a way to hide dangerous materials in electronics by replacing the battery space with dangerous materials.
The TSA say, “As the traveling public knows, all electronic devices are screened by security officers. During the security examination, officers may also ask that owners power up some devices including cell phones. Powerless devices will not be permitted onboard the aircraft. The traveler may also undergo additional screening.”
It’s a pain in the arse, but that’s the world we live in. Don’t let it put you off air travel. Charge everything up and give yourself plenty of time for the extra security checks.
