The wronged are the rest of the passengers on this flight, who were knowingly exposed to COVID-19 by this couple after they lied on a health declaration, and also delayed in their travels as a result of this couple's reckless behavior.
Since United does ask passengers to make a COVID declaration prior to the flight, I fail to see how UA can be held responsible for what happened.
If I were the airline, I would ban any passenger who boards a flight knowing that they meet the criteria for reporting a contagious disease and remain silent.
