An American law firm is encouraging consumers in the UK to claim compensation from companies found guilty of breaking competition rules.
The company's UK branch is looking to sue British Airways and Virgin for hundreds of millions of pounds after they were found guilty of colluding over fuel surcharges.
It's just been given permission to go ahead with a class action against both firms in the US.
While Virgin escaped punishment for alerting authorities about what was going on, British Airways was hit by a record fine of more than a £121m after being found guilty by the Office of Fair Trading. The US Department of Justice imposed another £150m.
