Today was my first experience of arriving in the non-Schengen area from a non-approved country, China in my case. The flight arrived at the F-pier at 6:30 am. Apart from the long walk to the security check everything went smoothly. There were only three people in front of me at the scanner and I was through quickly. Maybe I was just lucky. There is still a lot of building work after the scanners and I ended up walking down stairs and into the temporary access between piers E and F, which seemed a bit random. I guess the access into the halls will be improved once the building work is completed. As I was travelling onto the UK I cannot comment on the passport control for exiting or Schengen transfer.
