The ban on inflight electronics for flights from certain airports to the U.S. was a stupid policy even if the underlying concern was valid. It made planes less safe (due to the risk of lithium ion batteries in the cargo hold catching fire) without keeping electronics out of the hands of dangerous people heading to the U.S. who could fly Emirates via Milan or Athens or Azerbaijan Airlines from Dubai to Baku to New York JFK.
Including Abu Dhabi on the list of airports whose U.S. flights could not have electronics larger than a standard cell phone onboard was especially silly because Abu Dhabi has a U.S. preclearance facility.
