MailOnline reports that the woman, dressed in a BA uniform, filmed herself as she was about to fly from London Heathrow to Abuja on Friday.
The footage was recorded in her car and circulated among cabin crew who reported it to BA.
The airline said, “We expect the utmost professionalism from our staff when they are representing British Airways. We are investigating this video.”
Viewers were shocked when the woman said, “All Nigerians are going to be asking for f****** upgrades,” referring to the genitals of the men on board.
During the one-minute footage, filmed on Snapchat, the blonde female worker also revealed how she was going to deal with passengers on the six-hour flight.
A source told MailOnline that the video – which was captioned, ‘I can’t cope with this flight’ – was circulated among BA cabin crew only.
The yet-to-be identified woman filmed herself, saying, “Alright, so all of yous are there getting ready for your Friday night, getting in the pre-drinks, you know, as you do.
“And I’m here, getting ready to go to work, put on a yellow life jacket, point out the exits, hand out chicken or beef, what sort of Friday night is this for me?
“The upside is I’m going to Nigeria and there’s gonna be bare B**, I’m joking, I’m joking.”
The female could be heard discussing her upcoming flight and making racist comments about passengers travelling to Nigeria.
She said, “All the Nigerians are gonna be there like ‘gimme Coca-Cola, gimme me beef, why you have no beef left? I want beef.
“And I’m just gonna be there like, ‘Sorry sir, we ran out of beef.
“All the Nigerians are gonna be there asking for f****** upgrades because they haven’t got enough leg room because their B**s are in their way. Big d**** like this swinging from side to side.”
After shocked crew reported the video to British Airways, the airline launched an investigation.
