Delta Airlines has come under fire recently after failing to remove a passenger from a flight after he went on a pro-Trump tirade, calling other passengers on the flight "Hillary B*****s." Actress Gabrielle Union is set to travel via the airline tomorrow, and has taken to Twitter to issue them a specific warning following the incident.

The Almost Christmas star mentioned the airline on Twitter, warning them that she would easily be willing to boycott if they fail to do something about the incident, which they have, as of now, continued to ignore.

It is worth mentioning, though, that Delta's tagline, ironically enough, is "The world's most trusted airline."

Take a look at her tweet, below:

Delta is yet to respond.
