Before Lion Air Flight 610 crashed near Jakarta this week, apparently killing all 189 passengers and crew onboard, the Indonesian airline had been banned from flying in European Union air space between 2007 and 2016. It and all Indonesian carriers had been banned from United States air space for nine years until 2016. Aviation authorities in both the United States and the European Union based their evaluations on national standards of safety for Indonesian carriers compared to international standards. And both bodies said the country had cleared those hurdles.

Governing bodies in the United States and the European Union publish their evaluations of airlines, often by country, and provide resources for fliers when determining if their carrier is on a safety blacklist.

Here’s where to find those resources before you book.

Does the carrier meet United States safety standards?

The Federal Aviation Administration runs the International Aviation Safety Assessment Program, or I.A.S.A., which ensures that the country where a foreign carrier is based complies with safety standards established by the United Nations’ International Civil Aviation Organization (I.C.A.O.). I.A.S.A. evaluates countries based on eight criteria, including their aviation laws, operating regulations, civil aviation system and safety oversight functions, personnel qualification and training, and how safety concerns are resolved.
