No airline can avoid delays. Delays can occur depending on a number of different factors: airspace congestion, technical reasons, weather conditions and more.
Novair, together with your tour operator, will do everything possible to alleviate the effect of a delay.
Remember to allow at least 4 hours between any connection and your flight, both on the outbound and return journeys as delays may occur.
We therefor recommend you to book tickets that are changeable.
