CHICAGO (FOX 32 NEWS) - It was a warm reunion for this father-daughter pair, but a sobering one, knowing what's happening in their home country of Turkey.
"Very worried, I'm thinking I'm okay because she's inside the plane but I'm very worried because if something happened before it happened," Murat Orlu said.
His daughter, Yagmur, is visiting from Istanbul. She's worried about the family members she left back in Turkey.
"I feel terrible. I scared because of my mom is over there," Yagmur said.
Peter Jonkers is also visiting family and says he was shocked to see the news when the landed.
"It's scary because we were there, before that so its scary," Jonkers said.
Depaul University transportation expert Joe Schwieterman said Istanbul Airport, one of Europe's busiest, is very secure.
"Body searches, we see extra screening of baggage, those parts performed well today but it was the part outside of security that terrorists identified and it really was a vulnerable spot," Schwieterman said.
Schwieterman said this is a wake-up call for airports and we may soon see even more security.
"No doubt we are going to see more gates, screening as cars come into the airport, looking into bags, even superficially out there looking in the trunks of cars," Schwieterman said.
Jonkers agreed security seemed tight in Istanbul, saying they showed their passport at several checkpoints, now he hopes he can get back home safely.
"I'm glad I'm here I think it's better but we have a return flight home in a few weeks so I hope it stays calm there," Jonkers said.
Right now, if Jonkers was trying to go home, he wouldn't be able to.
The FAA has grounded all flights between the US and Istanbul. No word on how long that will last.
