As it says:
QUOTE from BBC News
"A number of airlines including British Airways are being investigated as part of a European and US cartel probe.
Investigators launched dawn raids, and British Airways said the European Commission and the US Department of Justice had asked it for information.
Other firms targeted include Germany's Lufthansa, Scandinavian airline group SAS, Air France KLM, and Cargolux." END QUOTE
What is this all about it says in the article but not deeply.
