Stringent security searches which have led to long delays and cancellations at Heathrow are not sustainable, airport operator BAA has warned.
The airport cancelled a third of flights on Saturday evening in a bid to speed its return to a normal schedule.
Tony Douglas, BAA's chief executive officer for Heathrow, said: "Quite simply I don't know how long it's likely to go on, but it's clearly a set of measures that are unprecedented and by virtue of what they've come in to enforce, they're not sustainable measures."
