I've been using Terminal 3 twice weekly for the last few months. With on-line check-in after a short walk from the railway station I'm in the departure lounge ten to fifteen minutes from arrival at the terminal. The staff seem to have made efforts to smooth the passage through security. A turnstile system gains entry operated by the barcode on your boarding pass. Staff are employed to help should you encounter a problem with this. There is a fast-moving queue for scanners. Shopping and food facilities are limited but adequate. Gates can be a bit cramped but I've yet to fail to find a seat. Signage is good. Arrival is no problem and there is a drop-off/pick-up area nearby so you can be away very fast. Long term on-site parking can be problematic as it gets very full but there are other options.
