WASHINGTON, DC (WBRE/WYOU) – A three judge panel has ordered the Federal Aviation Administration (FAA) to review whether airlines have made their seats too small in order to get more passengers onto their planes.

The panel also ordered the FAA to look at shrinking legroom for passengers, especially those who book economy class seats.

In a statement Saturday, the FAA said it is “studying the ruling carefully and any potential actions we may take to address the Court’s findings.”

Previously, the FAA has refused to mandate how much space airlines must ensure customers have on planes. But the judge’s decision will force the agency to revisit the issue.

The ruling comes after an advocacy group, Flyers Rights, petitioned the FAA in 2015 to implement new rules to regulate seat space.

The FAA refused to do so, so Flyers Rights, a passenger advocacy group, took its demands to court and won the right to move forward.

Federal judge in Washington D.C., Patricia Millet,writing for the panel said “As many have no doubt noticed, aircraft seats and the spacing between them have been getting smaller and smaller, while American passengers have been growing in size,”

Flyers Rights said it’s concerned that small airline seats are actually a safety hazard, putting passengers at risk for conditions like deep vein thrombosis. That’s a potentially fatal condition that can cause blood clots in people’s legs.
