In some cases of traveling on a norwegian cruise ship, you may have to go for the air-sea program. That program includes the cost of airfare from your city to the port where the cruise is to be boarded.

It is usually a two way arrangement, that is, the service is provided both at the time of going and returning. So, the next time you judge a cruise by reading cruise ship reviews on any travel portal like icruise.com, look into this point.
