You are right, i didn't realize that but it actually explicitly states that both the monthly and annual plans are eligible. I'm assuming this is likely funded in full by Uber.

Maybe a bit off-topic but this really seems like AmEx just declared open war on Chase and Citi. They are literally out to get blood. I can literally visualize all the "blogs/articles" in the next few weeks talking about how Chase and Citi are so lacklustre (especially given how much positive blogviews they got in the past few weeks)
