OK, so Kos airport is not that big, who likes waiting in airport anyway, we have been to Kos twice before first time in 2003 the second in 2005. We are coming to Kos again in May this year we don't like waiting in any airport so we just make the best of the situation and entertain our selves and be patient, we do not find any reason to mark this airport down it's the same in most countries, just make the most of it and have fun. I hope this will be of help to you.
We are coming back in May last time was in May 2005, we enjoyed it very much then and I know we will enjoy it just as much this time.
