It's an open secret that QR or DOH or some Qatari government-related entity has been subsidizing AA and other OW carriers to introduce service on their own metal to DOH, even if it competes with QR itself. AY serves HEL, CPH, ARN from DOH. IB and JL will soon join the club. As long as there is some arrangement to guarantee profitability, AA will continue to serve DOH even with a widebody shortage. PHL makes just as much (or just as little) sense as JFK, especially without feed from B6.
