I was approved for Chase Sapphire ($ 9,000 CLI) last month and have spent the $ 4,000 necessary to qualify for the 40,000 free miles. I tried booking a hypothetical flight to Cancun using the Chase Rewards System. Flight is listed for $ 450 whereas the same flight on cheaptickets.com is only $ 350.
I am new to the rewards game. Is there a card that one can use at any site?
