 More American Flights cancelled due to fear of Terrorism | |
A third airline has grounded a flight to the US for security reasons.
Continental Airlines has cancelled Sunday's 1215 GMT flight 17 from Glasgow to Los Angeles via Newark, New Jersey.
It comes after British Airways and Air France called off five US-bound flights on Sunday and Monday, amid fears al-Qaeda may be targeting them.
A US Department of Homeland Security spokesman said: "We remain concerned about al-Qaeda's desire to target international aviation."
He added: "There was specific credible threat information that was shared with some foreign governments, including the British and French Governments, and the decisions were made to cancel these flights."
US officials believe al-Qaeda is again trying to target international flights.
Continental spokesman David Messing said the Glasgow-Los Angeles flight was cancelled "because we were unable to obtain the necessary security clearance from the Department of Homeland Security and its international counterpart".
A BA spokeswoman said: "The safety and security of our operations is our absolute priority and will not be compromised."
Flights BA 223 from London Heathrow to Washington on Sunday and Monday have been cancelled as well as return flights BA 222.
BA flight 203 to Miami on Sunday was also grounded on security advice, as were four Air France flights to and from Washington. |
