I take my fins as carry-on in a green mesh duffle. That I found at a scuba shop, which stretches just barely long enough to fit my Cressi Gara 3000 HDs.

Generally the bag looks flat so people don't give you trouble flying with it becaues they look small, just be warned they go the back of the overhead bin, and people do put stuff in front or on top of them. Many holiday airlines in Europe have a discount rate (free or cheap) for taking diving gear on your flight. You have to check it, and reserve the luggage in advance and promise them you don't have any air cylinders or flashlights. I again put my long fins int the mesh duffel, inside a another diving backpack that has wetsuits, floats and stuff, but the fins stick out the op.

The Cressi's are pretty tough, I would be scared to treat a pair of carbon fins that way. I do pack them heel to tip (opposing directions so they support each other).

Never had a problem with my Cressis.
