Four former and current British Airways executives will appear in court next month over price-fixing on fuel surcharges which has already led to record fines for the airline, officials said Thursday.
British and US authorities have already fined BA a total of around 270 million pounds (340 million euros, 527 million dollars) over the offences which took place between August 2004 and January 2006.
BA's head of sales Andrew Crawley, former commercial director Martin George, former communications head Iain Burns and former UK and Ireland sales chief Alan Burnett could face jail sentences over the charges, the AFP reported.
George, Burns and Burnett resigned from the airline in 2006.
The world's major airlines are adding surcharges to their tickets owing to the soaring cost of kerosene, the fuel used to power jets that is refined from crude oil.
Crude oil prices struck record highs last month above 147 dollars per barrel but have since shed about 20 percent on fears of lower energy demand, analysts said.
A spokesman at City of London Magistrates Court said Thursday that the four men were "listed to appear here on September 24 in an Office of Fair Trading prosecution."
Britain's OFT watchdog body said they were "charged with having dishonestly agreed with others to make or implement arrangements which directly or indirectly fixed the price for the supply in the United Kingdom of passenger air transport services by British Airways and Virgin Atlantic Airways."
The four are among 10 past and present BA staff who have been refused immunity under a plea agreement between the airline and the US Department of Justice over the price-fixing.
The OFT fined BA 121.5 million pounds for colluding with Virgin Atlantic Airways on fuel surcharges on at least six occasions in the 2004-2006 period.
Virgin was granted immunity after bringing the matter to the OFT's attention.
BA was also fined 300 million dollars by the Department of Justice for a similar agreement with Korean Air.
In February, BA agreed to pay 136 million dollars in damages to passengers affected by the price-fixing to settle a US lawsuit.
BA chief executive Willie Walsh said this year that "any anti-competitive behaviour is to be condemned at BA or at other companies."
British Airways, which is currently in merger talks with Spanish airline Iberia, said last week that its net profit had plunged by 90 percent during the company's first quarter in the face of surging fuel costs and the economic slowdown.
"British Airways has received confirmation from the OFT that three ex-employees and one current employee of British Airways have today been charged with offences under the Enterprise Act 2002," the airline said in a statement.
