Mrs Gertcha and I passed through LGW South terminal on 17 November, around 9.45am. I have never seen a bigger queu for security. The queues went from both sides of the security entrance and the one that I joined started at the Thomson ticket desk in Zone A, then by the escalators upstairs was at least 6 people abreast.
Luckily, just as we got to the escalators, we were directed upstars to a new security area and got through quite quickly.
