SUB

Say you're eyeing a business-class redemption on a partner airline and need 100,000 points to make it work. You could spend the next year putting every purchase on a 2x card and grind out perhaps 50,000 to 60,000 points from organic spend, or you could open one card with a 100,000-point welcome offer and meet a $5,000 minimum spend in three months. The SUB collapses a 12-month earning timeline into a single quarter, which is exactly why it sits at the center of any serious points strategy rather than at the edge of it.

A common source of confusion is conflating the SUB with the card's ongoing earn rate. The earn rate is the multiplier on everyday purchases (2x on dining, 3x on travel, and so on). The SUB is a separate, one-time bonus delivered after you satisfy the minimum spend requirement. Readers also sometimes mix up "welcome offer" and "SUB" as if they describe different things; they are the same event, just different labels used by issuers and travel writers. A referral bonus, by contrast, is a smaller reward paid to the person who referred you, not to you as the new cardholder.

The mechanics that make SUBs so powerful come down to concentration and timing. Most offers require $3,000 to $15,000 in spending within a window of three to six months. Miss the deadline by even one day and the bonus typically does not post. Issuers also enforce "once per lifetime" or "once every 24 to 48 months" rules on many of their flagship products, so the opportunity to earn a specific SUB is genuinely finite. At our valuation of Chase Ultimate Rewards at 2.0¢ per point, a 100,000-point SUB represents roughly $2,000 in travel value, a figure that a single year of organic spend on even a strong everyday card rarely approaches. Exploring current top offers before applying is the most direct way to compare what is available right now.

The SUB is the highest-leverage earning event most travelers will ever encounter, so treat the application date and the spend deadline as hard project milestones, not suggestions.
