Delta has banned this man for life from its planes after a bizarre rant in which he shouted about Donald Trump and berated 'Hillary b****es'

The man asks loudly: 'We got some Hillary b***hes on here?'

Referring to Trump's victory, he says: 'If you don't like it, too bad.'

He then tried to goad other passengers into speaking up about which candidate they voted for.

The Atlanta-based airline had previously apologized over it, and CEO Edward Bastian said the passenger shouldn't have been allowed to remain on the flight.

The red card for the skies comes after the airline apologized for the shocking behavior on Saturday.

'We are sorry to our customers who experienced this disruption,' Delta said in a statement.

Epic rant: The Donald Trump supporter got out of his seat and started yelling out screams of praise for the president-elect on a recent flight, much to the shock of other passengers

'We have followed up with the teams involved and all agree that this customer should not have been allowed to continue this flight.'

The statement continued: 'Our responsibility for ensuring all customers feel safe and comfortable with Delta includes requiring civil behavior from everyone.

'The behavior we see in this video does not square with our training or culture and follow up will continue so we can better ensure our employees will know that they will be fully supported to make the right decisions when these issues arise.'

The video was viewed more than 2 million times since it was posted online, and it was widely shared across social media.

The passenger who filmed the incident said the man was eventually made to sit down after having been taken away by the flight attendants, but he offered one final thought when he took his seat.
