British Airways PLC said Wednesday that it will resume flights to Saudi Arabia from London in March after a four year break, citing the increasing importance of the oil market. BA said it plans to provide five flights a week from London's Heathrow Airport to both Jeddah and Riyadh. The carrier had suspended services on those routes in March 2005 because of poor commercial performance. "Resuming these flights makes commercial sense," said Robert Boyle, BA's commercial director. "The oil market is increasingly important globally and inward investment into Saudi Arabia has risen considerably in the last couple of years."
