The terror attacks Tuesday in Brussels created a heightened sense of security for fliers in the Hudson Valley.

Westchester County police said that while there was no increased presence at Westchester County Airport, personnel were on a high state of alert.

"At home we need to ensure that all our intelligence and law enforcement agencies are sharing information and working as one to keep people safe," Westchester County Executive Rob Astorino said in a statement.

Travelers, many of whom were heading out for spring break vacations, told News 12 that they refused to alter the way they live despite the attacks.

"We made a decision a long time ago that we weren't going to let anybody change our lives. We're going to keep living and take away that power," said Joanne Curtain Gaughan, of Mahopac.

"The security is very tight here. You can see the Westchester County PD is outside at the moment patrolling, so I feel very secure," added husband Mike Gaughan.

The departure and arrivals boards at the airport didn't show any canceled flights, but airlines advised travelers to check with their carriers about possible delays.

In the New York metropolitan area, security was more apparent at John F. Kennedy, LaGuardia and Newark airports, with the New York National Guard providing extra security detail at JFK and transit hubs. Flights to and from Brussels were suspended as the country began its mourning period.

The attacks, for which the Islamic State group claimed responsibility, left dozens dead and more than 200 people injured.
