Business Platinum vs Sapphire Reserve: which lounge card fits?

The real difference

Both cards start from Priority Pass, so the interesting part is what each adds. Business Platinum brings Centurion Lounge, Plaza Premium, Escape Lounges, and Delta Sky Club, with the Delta piece restricted to days you are flying Delta.

Sapphire Reserve takes a different route: alongside Priority Pass it opens Sapphire Lounge and the Chase Sapphire Terrace. Those are Chase-branded spaces, so the two cards have essentially no unique-network overlap beyond Priority Pass. Whichever proprietary lounge is in your terminal decides this comparison.

Where each card has the edge

Business Platinum costs $895 a year; Sapphire Reserve costs $795. The Amex card spreads its access across more brands, which matters most for travelers who move between many airports and want a fallback at each one. Delta loyalists get a further boost from the conditional Sky Club access.

Sapphire Reserve holds its own when a Sapphire Lounge or Terrace sits where you fly most, and it is the natural pick for someone who does not want a business card at all. Business Platinum is issued for business use, which is a practical filter before any lounge math applies. On international routes, the Amex card's Plaza Premium coverage gives it an additional layer the Chase card does not match.

Make the choice from real trips

Look up your next three airports on both card pages and count lounges you would actually enter. Then confirm enrollment for each network, the same-day boarding-pass condition on Sky Club, any visit limits, and guest pricing. Benefits shift over time, so verify the live terms before applying.
