Atmos Rewards — the shared loyalty program for Alaska Airlines and Hawaiian Airlines — has some of its strongest-ever welcome offers live across all three of its cobranded credit cards, and they're worth a look if you fly either carrier with any regularity.

The headline deal is the Atmos Rewards Summit Visa Infinite. New cardholders can earn 100,000 bonus points plus a 25,000-point Global Companion Award after spending $6,000 in the first 90 days — an offer The Points Guy values at up to $1,938. The catch is the $395 annual fee, but the card backs it up with 3 points per dollar on Alaska and Hawaiian purchases, dining and foreign-currency spending, a free checked bag for you and up to six travel companions, priority boarding, two Alaska Lounge passes and two Wi-Fi passes each quarter, and up to $120 toward TSA PreCheck or Global Entry every four years. One standout detail: it's the first card to award 3 points per dollar on foreign transaction purchases, which makes it genuinely useful for Americans living or spending abroad.

For lighter flyers, the Atmos Rewards Ascent Visa Signature costs just $95 a year. Its welcome offer is worth up to 80,000 points (60,000 after $3,000 of spend, another 20,000 after hitting $5,000) plus a $99 companion fare. You still get the free checked bag and priority boarding for up to six guests, 3x on Alaska and Hawaiian purchases, 2x on gas, EV charging, streaming, cable and transit, and an annual companion fare if you spend $6,000 in a card year.

Small-business owners have the Atmos Rewards Visa Signature Business: 70,000 points plus a $99 companion fare after $4,000 of spend, with fees of $70 for the company plus $25 per card. It earns 2x on gas, EV charging, shipping and transit, and uniquely knocks $100 off an Alaska Lounge+ membership.

Why it matters: the companion awards work on Alaska, Hawaiian and partner airlines including Oneworld members, so points can stretch to international redemptions in any cabin. If you've been sitting on an application, these bonuses are near record highs — but you'll need to hit the minimum spend within 90 days, so only bite off what your budget allows.
