WASHINGTON — A flight leaving Reagan National Airport was deplaned on Sunday after crew members expressed concerns about two passengers.

The American Airlines flight was headed to Boston’s Logan International Airport.

According to a statement from the airline, all the passengers deplaned, and law enforcement officers “performed additional security measures.”

No threat was detected.

The flight then departed for Boston, without the two passengers around 6:40 p.m.

The two passengers were questioned by police and released. Metropolitan Washington Airports Authority police say no charges have been filed.

American Airlines says the two passengers were “re-accommodated” on a later flight.
