Dao was on United Airlines flight 3411. The crew that bumped him was a Republic Airlines crew that needed to get to Louisville.

They are partner airlines and Republic was operating the flight for United.
you’re both wrong: it was United Express Flight 3411, contracted by United from another airline. The airplanes are not owned by United but are painted EXACTLY like United planes with the exception they say “United Express” rather than “United”.
