Ryanair are adding Ouarzazate 2x weekly from the end of March. I’d absolutely recommend it having been although no more than a short break is needed. It’s a top place for film fans as it’s home to Atlas Studios and the stunning town of Ait Benhaddou is half an hour or so away.
I don’t think this route will last too long however, I think it’s a bit too random and I’m guessing very few would have heard of it. When I went the only international route was a 1x weekly to Paris.
