croatia

First you need to plot out which cities in Croatia you want to see, and then you can figure out the logical arrival and departure airports. Croatia has airports in Zagreb, Split, Dubrovnik, Osijek, Rijeka, Pula, Losinj, Brac, and Zadar. The first three will have more connections available from places like London, Paris, and Frankfurt, and so will be easier to get to from Chicago. To find flights, use http://www.kayak.com/. You will probably want to fly into one city (say, Zagreb) and out of another (say, Dubrovnik). To find these, don't book two one-ways (much more expensive). Instead, choose "multi city" instead of "one way" or "round trip."
