| Never have I encountered airport personnel so cold and rude as on Keflavik! On my transfer from USA to EU, I was among the first passengers in line to board. I got pulled aside and asked to put my carry-on suitcase in the measuring bin. I was somewhat surprised at the request since my suitcase was lightly packed (not bulging) standard size designed to comply with all carry on regulations, which I have used for 15 years without any issues. The suitcase fit in the measuring bin without much trouble. Yet, I was informed that it was to be checked in because I had "guided it in" and it would not fit on the plane. I couldn't believe it! While the staff was fiddling with my ticket, I put it once again in the bin to make sure I was not hallucinating. Indeed, the bag dropped in with ease. The person processing me glanced at me and coldly with a note of sarcasm told me that: "This is of no use - your bag is getting checked!". Then it occurred to me to ask the second person on the counter if the airplane were a 767-300 and was told it was. "Well", I protested, "I just deplaned from a 767-300 and my bag traveled in the overhead bin with clearance to spare. This notion that it won't fit in the same plane is absurd!". At this point they caved, gave me an "approved carry-on" band and told me to just go on with my bag. Of course, by this time I had lost my place in the boarding line due to the lengthy delay. On my reverse transfer from EU to USA, after clearing passport control, I ended up on a lane where an official at a desk was checking passports again and questioning everyone before letting them proceed. I expected just a cursory inspection of my US passport and "good day", but got a rather lengthy interview with increasingly intrusive questions. After reviewing my passport he asked me if my first flight was fine. Then he proceeded to question me about how many years I have been living in the US. The next questions got even weirder: Do you like living in the US? He then asked me some somewhat more standard questions about my luggage: had I packed it myself and had anyone tampered with it? Later on while waiting in line to board, another agent went around and asked everyone the luggage packing and tampering questions and whether we had purchased anything from anyone outside of the duty free store all over again. All these "security" questions felt over the top. At the gate, I got a recap of my first transfer experience through the airport. Since my bag now had the "IcelandAir approved carry on" band on it, I did not expect any trouble when boarding this time. But no, the person past the counter asked me to drop my bag in the measuring bin (he already had a queue of passenger he had pulled over). I complied and when my turn came dropped my bag with finesse having gotten a lesson on it just a couple days prior. He was satisfied and let me go, but not after wasting a bunch of my time. Might as well have been last on the line. I have no idea what is going on in Iceland, but the airport staff are very cold and rude. They zealously try to force check-in innocuous standard carry on bags from random passengers as if they are on commission to do it. They also keep asking bizarre "security" questions - a throwback to the months after 9/11. This police state experience is such that it kills any desire to visit their country as a tourist ever. Thanks, but no thanks, Iceland!
