Approximately 5.5 Million people who flew British Airways and Virgin Atlantic may qualify for a refund as part of a class action lawsuit settlement. The lawsuit claims the airlines unlawfully conspired to fix prices for the "fuel surcharge" that was added to base ticket prices. Customers who purchased a roundtrip ticket on either airline between August 11, 2004 and March 23, 2006 are entitled to a refund of the fuel surcharge they paid, approximately $40 U.S dollars.The airlines are expected to release records of passengers flying during the time period in order to arrange for refunds, but have also set up an official website whereby potential claimants can provide their current contact information: http://www.airpassengerrefund.com/
