The BAA airport operator issued a memo demanding some 90 airlines reduce flights in order to allow for heightened security measures after last week's terror alert, The Telegraph reported.
In the memo, BAA chief executive Tony Douglas said airlines could lose the right to use the airport if they didn't comply, which reportedly incensed British Air's chief Willie Walsh, the newspaper said.
The airline has been forced to cancel approximately 900 flights since the terror alert was raised last week, and Walsh publicly accused the airport of being "unable to provide a robust security search process and baggage operation."
