We are flying out of PHL in January and typically use the Centurion lounge as our trips are international.

For the upcoming trip, we are flying to SJU in business and recent flights have left from Terminal C. We are not going to walk all the way to A to use the Centurion lounge.

My question is about AA lounge access. AA website is vague, stating business class tickets to the Caribbean allow access. Do flights to Puerto Rice fall under AA's Caribbean label?
