But it has now emerged that some budget airlines are not carrying out the new anti-terror security checks.

So what’s the score?

Reports today suggest that budget airlines like Ryanair and easyJet are not enforcing the new rules, with government refusing to make public exactly which routes are affected for security reasons.

An easyJet spokesman told MailOnline that the company was ‘aware’ that the security measures may be stepped up, but said the new rules did not yet apply to its passengers.

New guidelines were announced in the US last week after homeland security revealed that there had been a possible terrorist threat.

A spokesman for the Department for Transport said: “In line with the US advice, passengers on some routes into and out of the UK may now also be required to show that electronic devices in their hand luggage are powered up or face not being allowed to bring the device onto the aircraft.”

The government has confirmed that checks will be carried out on flights leaving and coming into the UK, but has not said which ones will be under scrutiny and it’s all very confusing.
