| This airport is a disgrace. As a UK citizen entering from the US and transiting to Manchester, we arrived in T3 and had to wait about 10 minutes for an operator to attach the airbridge. Once attached, we had a lengthy walk (about 15 minutes) to get to the UK Border and immigration check. Signage was OK but limited. Having been scanned at the ePassport barrier, I thought I was through and into the terminal proper but I was immediately confronted with another bank of scanners and bar code readers - no explanation or instructions. There was an unhelpful and surly security guard who stopped me from walking around these scanners. He told me that I had to (again) remove my glasses and have my photo taken for "airport security" - why? I asked him when my data would be removed from Heathrow's system. He gave me the impression he had no idea why I was asking and then glibly agreed with me that it would be deleted when I left the airport. I dont believe it for a moment. Given the recent court case about facial recognition software, where is the policy statement from Heathrow about the usage of our data and how it is protected/deleted? Once through this barrier, another lengthy walk to a bus gate for a long transfer to T5. Why does Heathrow not have a skytrain connecting terminals? After our overnight flight, we were made to wait about 30 minutes until a bus arrived at which point, there was a massive queue of people. The driver of the bus was rude, just packing people into the bus and then driving at quite a speed around a maze of roads to get to T5. We were then confronted with another walk to security where we again went through the usual street theatre of security, overseen by an unsmiling security guard - welcome to the UK. Had I been a foreign visitor, I would not have had a good impression of the UK. Once through the chaos of security, the shopping mall which is T5 was crowded with very few seats available and throngs of confused looking people. Eventually, we got to our connecting gate where our pictures were taken again before we were allowed to board. This airport is horrendous. Having flown in from JFK, I suggest that LHR management take a look at how a proper airport should be run.
