An Alaska Airlines flight was forced to make an emergency landing after the plane's engine cover began detaching.

The flight had just departed from Sea-Tac International Airport on Monday when the crew reportedly noticed an "unusual vibration."

Alaska Airlines Flight 558, which was headed for San Diego, returned to the Seattle airport and landed safely.

According to NBC News, no one was injured and the plane has been taken out of service.

The network reports that there were 176 passengers and six crew members on the flight.

The passengers were reportedly rebooked on another flight to San Diego.

Alaska Airlines said they've banned 14 passengers after a fight broke out during a mid-air flight from DC to Seattle.

In an email to EW Scripps, an Alaska Airlines spokesperson said the incident happened Thursday on Alaska Flight 1085 from Washington Dulles International Airport.

The spokesperson added that several passengers were "non-mask compliant, rowdy, argumentative, and harassed our crew members," and the airline banned 14 of them.

"Their behavior was unacceptable," the spokesperson said in an email. "We apologize to our other guests who were made uncomfortable on the flight. We will not tolerate any disturbance onboard our aircraft or at any of the airports we serve."

The in-flight incident comes a day after a deadly riot erupted after Trump supporters stormed the US Capitol.

On Thursday, American Airlines told EW Scripps in an email that they had increased staffing at DC-area airports as a precautionary measure.

As Trump supporters prepared to fly home Thursday after Wednesday's violent riot, the Association of Flight Attendants (AFA) issued a statement suggesting that those who flew into DC and participated in the Capitol's breaching should be banned from flying.

AFA linked to a video that showed issues arising on an American Airlines flight from Dallas to DC in that same press release.

Alaska Airlines added that they had banned 302 passengers for violating their mask policy since it went into effect on Aug. 7.

JUNEAU, Alaska (AP) — Alaska Airlines has banned an Alaska state senator from its flights for refusing to follow mask requirements.

An airline spokesman said Saturday that Republican Sen. Lora Reinbold, of Eagle River, had been informed and added the suspension was effective immediately.

Reinbold told the Anchorage Daily News that she had not been notified of a ban and that she hoped to be on an Alaska Airlines flight in the near future.

The ban comes after an incident last week at Juneau International Airport in which Reinbold was recorded apparently arguing with airport and Alaska Airlines staff about the mask policies.

The federal government requires masks aboard aircraft.
