Arrived at Terminal 7 left the jetway and joined immigration queue straight away. Took 3 hours to clear immigration along with some very confusing announcements made over the tannoy little done by airport staff or border staff to expedite queuing time. Terminal was overly hot. Not a great welcome! The only great thing about this was that we didn't have to wait for our baggage to arrive - staff were removing it from the carousel to make way for the next flight. On departure the terminal was more presentable however security closed a security lane despite a queue out of the queuing area arrived at desk to be told that the scanner wasn't working and that I'd have to get a new boarding pass although I skipped the 45min queue when I re- entered security. Terminal/airport nothing to write home about.
