Viking offers our United States guests the opportunity to purchase the Travel Protection Plan, administered by Trip Mate (a Generali company). The cost of the Travel Protection Plan (which includes assistance service fees) is calculated based on your Trip Cost. When you are searching for alternate flights or upgrading your flight itinerary to a higher class of service, the Travel Protection Plan cost would be calculated on these new fares and could result in an increase or decrease to total travel protection cost. Any travel protection cost changes will be communicated and confirmed before you are charged.
