This has been mentioned before but it seems worth mentioning again.
Navy Flagship Rewards offers 3x points on travel and 2x points on everything else. That’s the equivalent of 3% and 2% cashback, so it’s basically a 2% cash back card with 3% back on travel. (Travel includes ride-sharing, public tolls, public transit, and parking in addition to the normal airline and train tickets, hotel stays, and car rentals.)
Bonus offer is 50,000 points, or $500 when you spend $4,000 in the first 90 days. That’s the equivalent of 12.5% cash back, plus at least 2% more regular rewards.
$0 intro annual fee for the first year, $49 annual fee thereafter. Bonus and intro annual fee offer expires 12-31-18.
This reminds me of the Alliant Visa card, but with a bonus and the 3% travel and 2% everything else is permanent. You can cancel after one year if you don’t want to pay the annual fee for the second year (or you could think about the bonus as paying for 10 years of the annual fee).
