Long lines, more police at Chicago transit following Brussels attacks

Chicagoans are facing longer lines and an increased police presence Tuesday after the attacks in Brussels, which left at least 34 dead and more than 120 injured.

James Liskey, who was traveling at O’Hare International Airport Tuesday, is one of those who felt safe with “an increase in security.”

"I felt like we would handle it," Liskey said.

However, some had their travel plans completely scrapped.

Ruth Butler and her family were supposed to fly to Brussels Tuesday night for a family vacation, but in light of their canceled flight, opted for Orlando instead.

"With the kids around, it's just safety one of those things. We can try it again another time," Butler said. “They saw the news and so they were like ‘I don't want to go there’ I'm like ‘neither do we.’"

Chicago police said they are in contact with state and federal officials.

Ernest Brown, executive director at the Cook County Department of Homeland Security and Emergency Management, said they will be on heightened alert for the next few days.
