In the last few years the whole of the aviation industry has had to reassess its approach to security. Heathrow today faces threats that simply did not exist when our current terminals were built. The strict new security rules that are now in place are in response to genuine threats. The safety and security of our passengers and staff is, and will always be, our number one priority. We will do everything we can to protect them.

But we also know that sudden changes in security procedures at airports have made life difficult for travellers. We are determined that Heathrow's passengers should enjoy convenient flights as well as safe flights. That's why we are investing heavily to drive out queues across the airport whilst still maintaining high security standards. Since August 2006, we have:

• Recruited 500 new security officers at Heathrow
• Added 13 new security lanes
• Increased our overall security capacity by 25%
• Trialled body scanning technology in Terminal 4 and fingerprint and iris identification techniques in Terminal 3
• Continued to work closely with airlines and the UK's Department for Transport to take advantage of improvements in security technology.

Our target is that for 95% of the time security queues should be five minutes or less. BAA will invest the money and resources needed to get this right.
