Electronic devices larger than a cellphone will not be allowed in the cabin, though they will be allowed in checked baggage.
Size of the cell phone is not defined. The UK introduced similar ban, and they defined the dimensions of the cell phone allowed on the flight as no bigger than 16 cm x 9.3 cm x 1.5 cm [6.3 inches x 3.7 inches x 0.6 inches].
Who is impacted: For flights to the US, the electronic restriction applies only to direct flights on foreign carriers. The affected airlines are only foreign airlines flying from ten (10) airports in eight (8) Muslim countries. It is estimated 50 flights each day into the United States would be affected.
Who is NOT impacted: American-operated airlines from the affected airports, as well as aircraft crews are not impacted.
The list of affected countries and airports (There are 10 specific airports located in 8 countries):
Saudi Arabia (Jidda and Riyadh)
Qatar (Doha)
Kuwait (Kuwait City)
United Arab Emirates (Dubai and Abu Dhabi)
Turkey (Istanbul)
Jordan (Amman)
Egypt (Cairo)
Morocco.(Casablanca)
Neither of these countries is on the President's #MuslimBan list or #TravelBan or so called #LIstofSeven or #ListofSix, two recent executive orders.
At the same time, the British ban affects both domestic and foreign airlines, including British Airways, Turkish Airlines, Egypt Air, Royal Jordanian, and others. The British ban affects direct flights to the United Kingdom from Turkey, Lebanon, Jordan, Egypt, Tunisia, and Saudi Arabia.
The travel restriction is not based on any credible, specific threat of an imminent attack. Experts are divided over the need and effectiveness of the new travel restriction. It's not clear why only foreign airlines are affected, but not the US airlines.
