There's just one terminal at IFO, so you won't have to worry about getting lost. If you don't want to be rushed, arrive 1.5-2 hours prior to take off for domestic flights. If you're traveling internationally, we suggest arriving 2-3 hours in advance. This will give you enough time to clear security and customs and make your way to your gate. Add more time if you're traveling in peak periods, such as Christmas through to New Year's Day.
