I mean not much info on this route. They were all mega threads

I have excellent credit so getting a card wouldn't be problem. I have a World Points Mastercard but they are generic points or a cash redemption. I think you get a max of 1150$ for 80000 points. I'd say I am more interested in the upgrade aspect of things rather then getting free flights. According to that chart, I'm assuming you'd have to spend $210000 for a free first class flight. But if the cards come with free points when signing up then it'd be much more reasonable. I also have the Chase Rewards card you mentioned, but don't really use it. Thanks for the info!
