hours late due to the weather but then between the lounge and the plane we had 6 security checks. The man on xray was the most grumpy I have ever come across in an airport. Apparently they could see something they didn't like in my bag. They still couldn't work it out after passing it through the machine several times and getting me around to the screen to point it out. He then told me that 'he didn't have time to deal with all these stupid tourists that didn't know what to pack in their bags'!!! Luckily I remembered that I was in an airport and it wasn't a good idea to answer back!!! As he couldn't find what he was looking for they eventually let me carry on through to the gate. We had another check at the gate and then another one before we got onto the plane. Not quite sure where they think we would have picked anything up from! Fortunately 80 of us from the plane were on the same flight to London so the plane from Delhi to LHR was kept waiting for over an hour for us. The other passengers weren't so happy! Terrible for departures. Luggage was x-rayed twice, 4 total pat-downs, and twice everyone's bags were opened and searched. I don't see how anything could get in someone's bag from the gate to the airplane that would require two physical checks. Our plane left 2 hours late, partly due to all of
