This is the mortifying moment a furious passenger screams at cabin crew members to upgrade her to business class because she had 'pain in my t*ts'.

The unnamed passenger aboard a flight from St. Petersburg to Sharm el-Sheikh insisted that she needed greater comfort than her economy seat.

In an impassioned speech, the woman emphatically grabs her breasts as she shouts in broken English at an Aeroflot staff 'I'm in pain in my butt, I'm in pain in my t*ts'.

'I want business class,' she shouted at the implacable Russian crew aboard the six-hour flight.

'But I need a business class because I was working,' she pleaded in the video.
