Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

Limited-time offer. The Atmos Rewards Ascent Visa Signature Card is the one of the new refreshed Alaska Airlines cards in the new combined Alaska–Hawaiian ecosystem. Formerly the Alaska Airlines Visa Signature Card, and still issued by Bank of America. Note that you can now also use your “$99 + fees” Alaska Airlines Companion Fare on Hawaiian Airlines flights within North America, including to/from Hawaii, as long as the booking is made on alaskaair.com.

Right now, there is a limited-time improved 85k offer, which is usually also the one promoted by flight attendants inflight with their code handwritten on the flyer. However, any 7 digit promo code works on the application, and I’ve historically always gotten the bonus with any code.

Highlights:

• 85,000 Atmos points + $99 Companion Fare (must pay taxes & fees from $23) after $4,500 in purchases within the first 120 days of opening your account.
• Annual $99 Companion Fare. Get a $99 Companion Fare (must pay taxes and fees from $23) each account anniversary after you spend $6,000 or more on purchases within the prior anniversary year. Valid on all Alaska Airlines and Hawaiian Airlines flights within North America booked on AlaskaAir.com.
• First checked bag free on Alaska & Hawaiian (primary + up to 6 guests on same reservation). Any cardholder who purchases Alaska and Hawaiian Airlines airfare with their card, and up to 6 additional guests traveling on the same reservation, may check their first bag free.
• Preferred boarding. Primary cardholder + up to 6 guests traveling on the same reservation paid via this card can enjoy preferred boarding in group C before general boarding. Preferred boarding is only available on flights operated by Alaska Airlines, Horizon Air, or Skywest.
• 20% back on all Alaska Airlines and Hawaiian Airlines inflight purchases. Eligible in-flight purchases include food, drinks, and Wi-Fi.
• 3X points on eligible Alaska Airlines & Hawaiian Airlines purchases; 2X points on everyday categories like gas/EV charging, local transit & rideshare, cable and select streaming services; 1X everywhere else.
• 10% extra with Bank of America relationship. 10% bonus on points from purchases if you have an eligible Bank of America® or Merrill® account.
• Earn 1 status point for every $3 spent on purchases.
• No foreign transaction fees.
• $95 annual fee.

Bottom line. The Atmos Rewards Ascent Visa Signature® offers a unique set of perks for Alaska Airlines customers (along with Hawaiian Airlines in many cases), including free checked bags for more than just the primary cardholder and the “famous” $99 Companion Fare is still here as well.

I don’t receive any commission for this offer. I will be adding this offer to my ongoing list of Top 10 Best Credit Card Bonus Offers.
