Croatia is well served by Croatia Airlines (which is often reasonably priced, and offers a family discount for married couples, etc.) and by major international airlines. An option for budget travellers is to fly to London having bought a separate ticket from there to Croatia. The ultra-cheap airlines that operate out of London, such as Ryanair.com, do not fly to Croatia yet, but they made do soon. (At the moment, Ryanair flies to nearby airports in Austria and Italy, such as Venice and Salzburg.)
