With the attacks in Brussels last week and this week’s hijacking of an EgyptAir flight, airport security has many travelers talking.

Airports all over the globe are constantly updating their security measures to ensure that they keep their eight million passengers safe every day.

An aviation and aerospace professor at Metro State University described some of the ways airports are trying to keep up with these ever-evolving threats – a job, he said, isn’t the easiest.

Professor Jeff Price says there's never one solution to terror threats, especially in regards to aviation security. And that’s the challenge of it – as soon as one solution is reached, a new threat could be emerging.

“Unfortunately, it's just like the criminal,” Price said. “We come up with measures to protect our home, so they go and try and defeat those measures, so we have to have more measures to counter those measures.”

But Price said there’s certain things travelers can do to help themselves stay safe.

“You want to be an aware traveler, doesn't mean be a paranoid traveler,” Price said. “You're not going to be able to operate at that level for a long time. Just be aware of your surroundings.”

The Metro State professor said the best thing to do is trust your instincts. If you see something that doesn’t sit right with you, move away from the area and say something to law enforcement.

Airport security will most likely continue to be a hot topic with peak travel months approaching.
