With flights operating from just one passenger terminal at Kazan Intl. Airport (KZN), there's little chance of getting lost here. Look up the airport's official website to find out what services and facilities are available to departing passengers. Get your vacation started on the right foot by arriving 1.5-2 hours ahead of domestic flights. For international routes, you'll want to arrive 2-3 hours before your departure time. Both recommendations take into account possible delays at security or customs, time needed to check in bags and navigating to your gate.
