Having used GVA twice a week since January I can say that it is on the whole a pleasant experience. I always check-in online and so bypass the check-in desks but I can imagine that during peak periods it can be a frustrating experience the same can be said for security. I mostly travel during the early/late afternoons so security is rarely busy when it is I find it efficient and the staff courteous. My only gripe is those passengers that block the conveyor with their trays even though there are signs saying to keep moving. Once through security the departure area is airy and fairly well designed if you want to get away from the crowds follow the signs to the smoking lounge on the upper floor there is plenty of seating outside this lounge and it is never busy. I do find that the food is expensive and overall duty free is really no bargain.
