The airline publicly stated that hate-related or hostile behavior is unacceptable and initiated disciplinary actions. This grounding is part of a broader response that also involved Delta Air Lines suspending pilots for similar conduct.
The Transportation Secretary Sean Duffy condemned the celebrations, highlighting the seriousness with which such workplace conduct is treated.
