Croatia Airlines Operating Partners

Not every flight with a OU number is actually Croatia Airlines. These partner airlines operate routes under the OU code. Your booking and flight number say OU, but the plane and crew belong to one of these carriers.

On shorter routes from the hubs, this usually means a regional jet. Smaller plane, tighter bins. Check the aircraft code when you book. If it says E175, CRJ, or ATR, that's a partner regional jet.
