This is a terrible airport - I have been here many times and it is always equally bad. For example, today we got here with plenty of time but the queues were so big that we almost missed our flight. When I asked whether we could skip the queue since our gate was closing in 5 mins, the security lady was extremally rude a defensive saying things like it s not my fault rather than trying to resolve the situation. Even when people allowed us to go through in front of them, she stopped us from doing that. Just terrible - airport is totally not made to accommodate London s needs in terms of dealing with flights and is so badly organised. If I could I would give it zero stars after today.
