The fasten seatbelt sign is on, and 2024 looks like it will continue to be a bumpy ride for Boeing.

Concerns about flight safety are currently heightened after a mid-flight accident last week resulted in a panel flying off a Boeing 737 Max 9 operated by Alaska Airlines after it left Portland, Oregon. This marks the latest in a series of safety issues for the aerospace company, some of which have been deadly for passengers in recent years.

In the U.S., air travel is typically safer than traveling on the roads. Although global data suggests the risks for flight accidents are low, annual fatalities associated with air travel accidents show that boarding a plane still comes with risk. The European Union keeps a regularly-updated list of airlines that are banned or restricted from operating within the regional block due to safety concerns.

While this list is not a direct reflection of accident or fatality rates in the skies, it’s regularly reviewed by experts on the European Commission to assess which airlines meet international safety standards.
