About C3
C3 is a Croatian regional carrier operating a tight domestic network across six airports — all of them inside Croatia. With 12 non-stop routes and a total network span of just over 3,200 km, this is a small airline built for short hops, not long hauls. Osijek (OSI) anchors the operation as the main hub, with Split (SPU) pulling equal weight at three routes each. If you're trying to move around Croatia quickly without renting a car or sitting on a bus for four hours, C3 exists specifically to solve that problem.
Why fly C3?
Honestly, the case for C3 is simple: it connects Croatian cities that are genuinely annoying to link overland. The country's geography — coastal cliffs, islands, mountains cutting inland routes — makes driving between places like Rijeka (RJK) and Osijek (OSI) a half-day commitment. Flying changes that math completely. For travelers already spending points or cash getting into Croatia internationally, a domestic C3 leg can the kind of multi-city itinerary that makes a trip feel twice as big. You're not flying C3 for a luxury experience or a frequent flyer program. You're flying it because it gets you somewhere faster than anything else on the ground, and in Croatia, that's worth real money.

Tips for booking C3
The network is 100% domestic Croatia, so don't expect international connections through C3 metal — you'll need a separate ticket for that. Book your C3 leg independently and leave yourself buffer time if you're connecting from an international arrival. The longest route in the network is PUY to OSI at 388 km, which tells you these are short flights — pack light and check baggage policies carefully before assuming anything fits overhead. Pula (PUY) and Rijeka (RJK) are both smaller airports, which means faster security and less stress. If your Croatian road trip keeps expanding, C3 is worth checking before you default to another rental car day.
