Naxos is a very small airport (one gate small). As we all were waiting to board we saw the airport crew load all the luggage, 15 mins goes by and they all were talking with each other and something looked wrong. Then we saw the pilot come around and talk with the crew, this went on for about 5 more minutes. We were about 15 minutes delayed at this point. Then the crew starts unloading the luggage, so all of us waiting figured the flight was getting canceled. Nope, they started boarding us. Several of us asked multiple ground crew and on plane staff "What's going on with our luggage?" No one would answer or even acknowledge. Get to Athens and no luggage. Not a surprise as we saw them pull our bags and we have tile trackers in them. Stand in line hour plus to file out claim. Zero care from any staff that over half our flight is filing claims. "This might be a few days" we get told. If you have already left the county they will be shipped to your home in a few weeks. Get told we will get updates via text message and email. Need to spend our first night in Athens shopping for clothes and necessities for the next day. Wake up with no updates from the airline but my location tag says it was at the port of naxos (not the airport, the boat port). A few hours later my wife's bags location tag says port of Paros, a different island. Still no updates from Airline. My wife and I do a tour, in our new clothes, and after see our location tags at Athens airport. Still no communication from Airline. We call twice and are on hold for 30 minutes each time with no answer and their system hangs up on you after 30 minutes. We go have late lunch and think about driving the 45 minutes to the airport to get them ourselves. Decide we will call one more time when we get back to hotel. When we get back, our luggage is sitting in lobby of hotel. Never once was contacted by Airline. We will never fly with them again and will advise everyone we know to stay away as well.
