My friend and I will be taking a shuttle from Ljubljana to the Zagreb airport for a 10:35 flight to Dubrovnik. How early should we be at the airport? thank you!
I always aim for at least 90 minutes before flight departure, even for domestic flights.
I would concur that at least 90 mins. would be sufficient. We did the opposite- Dubrovnik to Zagreb. As I recall we arrived under 2 hours for our departure.
Zagreb is a small airport, and this is a domestic flight. I wouldn't get there more than 90 minutes ahead. An hour would probably be plenty, but of course you never know what kind of delays you might encounter. Better to be a little early...
