FORT WORTH (CBSDFW.COM/CNN) – Fort Worth-based American Airlines says it is taking new “precautionary” measures after rioting in the nation’s capital — including no longer serving alcohol on flights to and from Washington, DC.

The action comes as one union reported several incidents during which flight attendants “were forced to confront passengers exhibiting politically motivated aggression towards other passengers and crew.”

“We are working closely with local law enforcement and airport authority partners to ensure the safety of our customers and team members on the ground and in the air,” the airline’s statement said.

The airline did not provide details on specific incidents, but the announcement came on the same day thousands of Donald Trump supporters rioted and stormed the US Capitol as Congress kicked off its joint session to certify President-elect Joe Biden’s victory.

In a message to union members, the president of the Association of Professional Flight Attendants said union leadership was aware of incidents on multiple flights headed to DC.

“As safety professionals, we are well trained in handling inflight disruptions, but we should never find ourselves having to deal with politically motivated verbal or physical altercations onboard,” the message said.

Flight attendants have been directed to continue to “maintain situational awareness, and attempt to deal with all safety and security issues on the ground.”

“Remain extra vigilant on flights departing from the Washington, D.C. area for the next few days, and involve your fellow crewmembers if you have safety concerns.”
