Bankrate’s Take
Since the rewards from both cards can be combined, you could use the rewards you’ve earned from your business spending to help cover the cost of your personal travel while enjoying luxury benefits like airport lounge access, status with Marriott Bonvoy and Hilton Honors, and reimbursement of up to $120 for your CLEAR Plus, Global Entry or TSA PreCheck application fees.
When your business takes you across the world, the combination of the American Express Platinum Card and the Blue Business Plus could help you stretch your credit card rewards further while tacking on some luxury benefits.
