Both itinerary have the same confirmation code, and when I pull it up on the JAL website it shows us having seats in both business and premium economy on the same flight, same date, ORD-HND. We would obviously prefer to fly in business, but who should I contact to get this sorted out (hopefully favorably, since we originally booked premium econcomy) ... or do we do nothing and show up and fly it as booked? Would you recommend reaching out to JAL or American Airlines customer service?
