Do you have the personal or business Amex Platinum and never know how to use the $200 airline credit? I found the cleanest way to use it and you’ll stop leaving $200 on the table every year ✈️💳 1. First you’ll go to your Amex benefits page and pick United Airlines as your airline 2. Then add money with your Amex Platinum to the Travel Bank and do two $100 deposits to your United Travel Bank 3. You’ll then see Amex reimburses you $200 for those two charges 4. Your credit now lasts up to 5 years,
