Olkiombo Airport (OLX) operates from a single terminal building. Wondering how to make time go faster before you're cruising at altitude? Do some research online to learn what types of amenities and services are available. To be on the safe side, arrive 1.5-2 hours prior to departure time for domestic trips. If you're flying internationally, we suggest arriving 2-3 hours in advance. This will give you enough time to be checked by security and customs and then head for your gate. It's smart to add extra time if you're traveling in peak periods, such as Thanksgiving and New Year's.
