I am a frequent user of the airport (about once a month on average) The airport is generally very efficient. The only drawback being the often very long (and slow) queue to security and sometimes to the check in. The latter are the bottlenecks. Security is often understaffed and this is a long standing and notorious problem at this airport. My experience is that all staff are generally very polite and helpful and often friendly too. Walking distances are notably long though walkways are provided. The best feature is the baggage reclaim - it is extremely fast and it is not uncommon for your luggage to be at the reclaim before you arrive there. Free WiFi is provided. The business lounge is frequently overcrowded. All other facilities are first class.
