The steps that can take you from $2,152 to $1,766 in Business Class (if not much better) all day long.
In March FCF updated you on the AARP membership discount on British Airways First and Business Class tickets: It was reduced from $400 to $200.
But from now until Dec. 31 there’s a way to claw back some of that savings with the British Airways Visa card benefit of 10% off, using promo code CARDOFFERU (the 10% discount will most likely be extended at some point into 2018).
Sample Savings: On New York-Dublin, the lowest Business Class fare is currently $2,152, but with the combined discounts the price comes to $1,766, a savings of $386. (See screenshots below.)

How to work it:
Step #1: Log in to your AARP account: (Costs just $12 for anyone of any age to join) to get the $200 AARP discount for Business Class, then…
Step #2: Click to go to BA’s website, select your flights, then click the confirm-the-flight-and-fare-details, add in the 10% Visa discount code (CARDOFFERU), and purchase the ticket with your BA Visa card.
Note: The Visa discount is also valid for up to eight friends and family members traveling on the same itinerary, but only on British Airways-operated flights or on OpenSkies.
