The consumer association Flyers Rights filed a legal action at a court in Columbia of the US Court of Appeals in recent days. In the documents it asks that the Federal Aviation Administration (FAA) establish as soon as possible minimum standards for the width of seats on board commercial aircraft, as well as the space between rows in multiple-aisle aircraft. 

From November 2019 to January 2020, FAA conducted tests to determine whether aircraft cabin configurations, which have become increasingly dense with seats over the decades, can be evacuated within 90 seconds, as required by federal law. The authority has not released the results. 

The users point out that, as mandated by the US Congress in 2018, US regulators should have set such standards by Oct. 5, 2019. According to the consumers' allegations in two years, the agency has yet to initiate the regulatory process, which by law is supposed to establish what minimum spaces protect "the safety and health of passengers" .
