Citing a drop in demand, the Dubai-based, United Arab Emirates-owned airline Emirates Air announces a cut in flights to five of its 12 U.S. destinations. The airline’s Dubai hub, third-busiest in the world, is a major stop for travelers in countries affected by President Donald Trump’s travel ban, and is also one of several Middle East airports affected by a U.S. ban on tablets, laptops, and similar devices in the passenger cabin.
