Gotta wonder why OP wants specifically to fly Norwegian when he or she knows about points. Wouldn't it be better to get a couple of cards with big bonuses on UAL or AA etc and use the bonus points to fly on the many different airlines available when you have such miles. Or get a couple of Chase cards (INK and Sapphire Preferred, for example) and use the Ultimate Rewards points to transfer to one of the many available airlines.
Why does it have to be Norwegian?--why limit your options?
