As announced yesterday by Secretary Kelly, the U.S. Department of Homeland Security (DHS) is implementing heightened security measures to address ever-evolving threats to commercial aviation. DHS has worked with industry and foreign partners to develop an effective mitigation strategy while minimizing disruptions to the traveling public. There are no changes to items allowed in carry-on and checked baggage. However, passengers flying to the United States should prepare for a more extensive screening process, including the enhanced screening of personal electronic devices (PEDs) larger than a cell phone. Additional measures, both seen and unseen, will be implemented in phases over the next several weeks and months in coordination with international partners. Aviation stakeholders who do not fulfill the new requirements within certain timeframes may be subject to additional restrictions being imposed, including a future ban on large PEDs on aircraft.
