Today’s crash of Spanair flight JK5022 upon take off at Madrid’s Barajas Airport was the latest in a series of recent air disasters that have anxious passengers wondering about airline safety.

The cause of the crash, which killed at least 153 of the 172 people on board, has not yet been determined.

While most aspects of flight safety are beyond passengers’ control, experts do offer some tips to frequent flyers:

Choose non-stop flights over multi-stop routes: Because most accidents, like today’s crash, occur during take-off or landing, reducing the number of take-off and landing events decreases the likelihood of crash potential.

Choose larger planes over smaller ones: In major accidents, larger planes with greater passenger capacity offer statistically significant survival advantages compared to planes with fewer than 30 seats.

Know your emergency exit: Simple enough, and though it won’t always save your life, it may increase your chances.
