Alaska Airlines' premium Atmos Rewards Summit Visa Infinite card has rolled out a limited-time sign-up offer that punches well above what most big US airline cobrands are dangling: 100,000 bonus points plus a 25,000-point Global Companion Award, if you spend $6,000 in the first 90 days. The annual fee is $395.

The companion award is the part worth understanding. It knocks up to 25,000 points off the cost of a second passenger's award ticket on Alaska, Hawaiian or partner awards booked through Alaska's site, in any cabin. So a pair of 35,000-point tickets drops from 70,000 points to 45,000, and on pricier redemptions the maths gets better still: two 100,000-point tickets fall to 100,000 points total. You get a fresh 25,000-point certificate every account anniversary with no spending requirement, and spending $60,000 in a card year unlocks a separate 100,000-point version. You can hold and use both.

The fine print matters. Both travellers must be booked together on the same itinerary, and only new bookings qualify — you can't attach a certificate to an existing reservation. One-way and round trips work; multi-city and open-jaw itineraries don't. The cardholder doesn't even need to be one of the travellers. Book within a year or the certificate lapses.

Where this card genuinely separates itself is foreign spending: 3 points per dollar on eligible overseas purchases, alongside dining and Alaska or Hawaiian ticket buys, with 1 point per dollar on everything else. Hold a qualifying Bank of America or Merrill account and a 10% relationship bonus lifts those to 3.3 and 1.1. Few airline cards reward spending abroad at anything above the base rate, so frequent international travellers should pay attention.

Other benefits stack up in practical ways. The card waives Alaska's $20-per-person, per-way partner award booking fee when you pay taxes and fees with it — $80 saved on a round trip for two, meaning five such bookings cover the annual fee on their own. You also get eight Alaska Lounge passes a year (each admits an adult plus two kids under 21, issued two per quarter and expiring quickly), eight Wi-Fi passes, a free first checked bag for the cardholder and up to six companions on the same reservation, 20% back on eligible onboard purchases, up to $120 towards Global Entry or PreCheck, and a $50 voucher for qualifying delays. Free points sharing between up to ten linked Atmos accounts is handy for families pooling balances.

There's a status angle too: the card earns one status point per $2 spent, plus 10,000 status points each anniversary. Combine $60,000 of annual spending with that anniversary deposit and you reach Atmos Gold — which maps to oneworld Sapphire.

Is $60,000 of spend worth it compared with a straightforward 2x-everything card? You'd forgo roughly 54,000 points in exchange for the big companion certificate and the status credit. For households who actually fly Alaska or Hawaiian and can find award space for two, the answer is often yes.
