British Airways is currently offering fares from a number of U.S. cities to Dublin in business class for $2,022 roundtrip on many days during the summer.
Additionally AARP members (anyone can join here) receive $400 off British Airways business class tickets. British Airways cardholders also get an additional 10% off with the code CARDOFFERU.
After all discounts, the final price for the ticket should be $1,460. This ticket should also qualify for the American Airlines premium cabin bonus when credited to AAdvantage. With that bonus you would receive an additional 20,000 mile bonus.
