Security Message for U.S. citizens:  

Kingdom of Belgium Reduces Threat Level from 3 (probable attack) to 2 (heightened concern) - March 9, 2015

Enhanced Security Measures at the Airport 

The Department of Homeland Security (DHS) continually assesses the global threat environment and re-evaluates the measures taken to promote aviation security. As part of this ongoing process, DHS Secretary Jeh Johnson has directed the Transportation Security Administration (TSA) to implement enhanced security measures for departures to the U.S. from Brussels National Airport (BRU).  During the security examination, officers may also ask that passengers power up some of their electronic devices, including cell phones.  Powerless devices will not be permitted on-board the aircraft.  Passengers are encouraged to charge their electronic devices prior to arrival at the airport and to allow extra time for screening.
