Alaska Airlines and Hawaiian Airlines have debuted the Atmos Rewards Summit card with a six-figure bonus, companion awards, lounge passes and travel perks.

Alaska Airlines is launching a $395-a-year rewards credit card as it joins the industry's race for high-spending customers. It is also launching a combined loyalty program with Hawaiian Airlines, called Atmos, and raising requirements for elite status. Alaska acquired Hawaiian last year and plans to keep the two brands operating separately.

Credit cards can yield valuable travel rewards. These are some of the newest offerings on the market as well as recent promotions to pad your account.
