*I am posting this also in the 'transportation' forum since I wasn't sure which one would be more appropriate.
I've used my Mileage Plus Chase card to travel economy, business, and first class over the last 5+ years. My mom has a Chase Sapphire and I'm debating whether to switch. I've looked at a few websites that compare the two cards. My understanding is that with the Chase card you build up points and then when you decide to travel, you buy your ticket from a travel agency and Chase credits your account the amount of miles you have as a dollar figure towards the price of the ticket. So if you're purchasing a business class ticket at $6000 and you have 6000 points, it's credited back to your account.
My question is when you use your Sapphire card, do you get 1=1 or dollar for dollar in 'points'? If so, I'm thinking it's a better deal than with my Chase Mileage Plus, where I get 1=1 for most purchases but it costs me 25K for a domestic flight and (at times) 150,000 points for a business round trip flight. And I can't always get the flight I want. Any help or suggestions or corrections as to how I'm viewing the two cards would be appreciated.
