There is only one terminal building at HRK, so you won't need to rush between terminals for a connecting flight. Avoid racing to your departure gate, or worse, missing your flight, by arriving 1.5-2 hours ahead of domestic journeys. You should arrive 2-3 hours ahead if you're traveling internationally. This will allow you enough time to check in bags, pass through security and customs and make your way to your gate. We also recommend checking the arrival time recommendations of both your airline and departure airport.
