New JetBlue Card with All-Time High Sign-Up Bonus

A new public offer on the JetBlue Plus Mastercard from Barclays delivers 40K points for $1K spend in the first 90 days. The offer is valid till the end of January next year. This is an all-time high sign-up bonus for this product to-date, so if you've been thinking about signing up for a JetBlue card to snag some points, you're not likely to see a better offer for at least a year and maybe more.
