Norwegian Air's loyalty program, Norwegian Reward, has just announced its new official car rental partner, Avis Car Rental. The new partnership will let Norwegian Reward members earn points toward cheaper or free Norwegian flights when they make car rental reservations around the world with Avis at www.norwegianreward.com.

Starting immediately, Norwegian Reward members can earn up to 10% CashPoints and enjoy up to a 15% discount when they book car hire with Avis through the Norwegian Reward website. Also, members can add an additional driver at no extra cost and claim missed CashPoints up to six months after their car rental has ended.

To take things up a notch so Norwegian Reward members enjoy even greater value, frequent Norwegian Air flyers can look forward to receiving an invitation to join the Avis Preferred Plus tier within the Avis Preferred loyalty scheme, for at least a year. All they need to do is fly more than six Norwegian Air flights in a year. Norwegian Reward members who complete 18 or more Norwegian Air flights in a year will receive an invitation to join Avis President's Club for at least one year.

But of course, a higher level of membership comes with more benefits, including perks like complimentary upgrades whenever available, priority service, priority for car availability, accelerated rewards, exclusive offers and more.

For those who do not already know, all CashPoints earned can be spent toward the cost of Norwegian Air flights, including all flight taxes and extras. CashPoints are valued approximately 10 to £1, dependent on currency exchange rates.

At the moment, there are over 8.3 million Norwegian Reward members worldwide, 1.2 million in the United Kingdom. So, plenty of Norwegian Air customers will get to benefit from Norwegian Reward's latest partnership with Avis, one of the most renowned car rental brands in the world with around 5,500 locations in approximately 170 countries.
