Kate Winslet is reportedly upset with the lack of security at British Airways — in the carrier’s frequent flier department. London’s Mail on Sunday reported that a BA Air Miles employee has been fired for handing out Kate’s home number. The gaffe was discovered, says the Mail, when the “Titanic” star’s home phone rang and she asked the caller how he got through. “I’ve got a friend at Air Miles,” he reportedly replied. An investigation produced the culprit, who was fired on the spot. BA is now said to be tightening its security — and footing the bill for Kate to change her phone number.
