First, the United States and later British government announced a cabin baggage ban for electronic devices larger than mobile phones on direct passenger flights to their countries from eight majority-Muslim countries.

For an indefinite time, passengers on non-stop flights to US and UK will have to put their laptops, tablets, Kindles and portable game consoles into their checked baggage. The restrictions would not apply to aircraft crews.

The new policy took effect in the US at 3 a.m. E.D.T. on Tuesday, and must be followed within 96 hours by airlines flying to the United States from airports in Amman, Jordan; Cairo; Istanbul ; Jeddah and Riyadh in Saudi Arabia; Kuwait City; Casablanca, Morocco; Doha, Qatar; and Dubai and Abu Dhabi in the United Arab Emirates.

U.S. airlines aren’t affected by the new ban on electronics since none fly non-stop to U.S. from any of those countries. However, 6 UK carriers will be affected by its government’s travel ban. They are British Airways, EasyJet, Jet2.com, Monarch, Thomas Cook, and Thomson. Other international carriers that will be affected are Turkish Airlines, Pegasus Airlines, Atlas Global Airlines, Middle East Airlines, Egyptair, Royal Jordanian, Tunis Air, and Saudia.

The ban will affect passengers who booked cheaper, hand luggage-only tickets, but would now have to pay to check a bag in.

Turkish Airlines will be one of the hardest hit by the new ban since thousands of passengers use the carrier every day to fly from long-haul destinations via Istanbul.
