American Express has rolled out one of the biggest welcome offers around on its Business Platinum Card: up to 300,000 Membership Rewards points after spending $20,000 in the first three months. At a conservative valuation of about 1.7 cents per point, that's roughly $5,100 in potential travel value — enough to get most people's attention.
Here's how it works. You fill out the application and Amex presents a targeted offer, which may be lower than the headline 300K depending on your card history, spending and past bonuses. Checking the offer doesn't affect your credit score; only accepting and proceeding triggers a credit pull. If you're shown a lower bonus, it's worth rechecking periodically or looking at targeted emails, since Amex adjusts offers over time — though don't expect a different result purely from applying through another link.
The spending requirement is the real hurdle: roughly $6,700 per month for three months. Anyone with big upcoming business costs — inventory, ad spend, equipment — can time an application around them, or prepay expenses. Just clear the balance in full to avoid interest eating into the value. Points typically post within 8-12 weeks, often faster.
What can 300,000 points actually buy? Two options stand out. The card's Pay With Points benefit gives a 35% rebate on airfare booked with a designated airline, up to a million points per year — so 300,000 points could cover around $4,620 of flights. Alternatively, transfer to airline and hotel partners for premium cabin redemptions; 60,000 points to Flying Blue books a one-way Air France business class seat from Miami to Paris, with roughly $337 in taxes.
Eligibility follows Amex's "once in a lifetime" rule: you can't have held this card or its predecessors before, but holding other Amex cards is fine. You don't need a registered company — freelancers, side hustlers and landlords qualify as sole proprietors. Approval is reportedly relatively easy, with scores around 700+ preferred but not mandatory, and the card doesn't count toward Chase's 5/24 rule.
The catch is the $895 annual fee, which is steep but offset by a long list of credits: up to $600 a year on hotels booked through Amex's premium programs, $1,150 at Dell, $250 at Adobe, $219 for CLEAR+, a $200 airline fee credit, $120 for Global Entry or TSA PreCheck, plus credits for Indeed, ChatGPT Business, Hilton and wireless bills. Add Centurion, Delta Sky Club and Priority Pass lounge access, Hilton and Marriott Gold status, and no foreign transaction fees, and the card can pay for itself for someone who actually uses the perks. Spending $250,000 a year unlocks further credits worth up to $3,600.
For business owners who travel — or want to start flying business class on points — this is one of the strongest entry points into the Amex Membership Rewards ecosystem right now. The 300K offer won't last forever, so it's worth checking what you're targeted for before it disappears. — One Mile at a Time
