Update: Some offers mentioned below are no longer available. View the current offers here.Last week, Chase introduced the much-anticipated Sapphire Reserve Card, and I was fortunate enough to receive my card a couple days later. The perks are absolutely fantastic (we detail them here), and include a $300 travel credit issued each calendar year.Unlike with competing premium travel rewards cards, however, the Reserve card’s $300 credit applies to any travel purchase, so I decided to take it for a spin with United’s “award accelerator” option. I ended up purchasing 45,000 United miles for $900 (a reasonable 2 cents per mile), which I could end up using toward a redemption in United’s soon-to-be-released Polaris business class (pictured above).Much to my surprise, the credit posted instantly — as in, it hit my account the very same day the $900 purchase posted. That means you won’t need to make an eligible purchase and pay it off only to get the credit a few weeks later. And while a potential delay wouldn’t be a “make it or break it” detail, it’s certainly better to have your credit sooner than later.Have a question about the Chase Sapphire Reserve Card?
