United Airlines has confirmed that Captain Ibrahim R. Mossallam is being withheld from flight duty pending an internal review, AeroTime reported. The pilot previously faced scrutiny over social-media comments about the October 7, 2023 attacks and later returned to flying. United has not explained whether the latest review concerns new posts or other conduct.

Additional media claims about fellow pilots monitoring him from the cockpit and union intervention have not been independently verified. The reports do not identify the relevant flight, date or pilots. The confirmed development is a duty restriction and review, not a proven flight-safety incident or an announced dismissal. Unverified allegations should remain clearly distinguished from the airline's statement.
