DCA-JFK. Truly appalling experience. Apart from the 2.5 hrs delay due to which I missed a connection display of apathy indifference and condescension from multiple employees. The ground staff at DCA couldn't even advise if the incoming plane was in the air or not instead kept drip-feeding announcements of 30 mins delay each time. The lady didn't even have the decency to call JFK and explain my situation. At JFK in the middle of the night no AA staff was to be found finally a supervisor appeared at 5am and just sniggered at my problem of having missed the flight to Korea - not their problem apparently. The plane was shabby dirty and windows were barely kept together with a sticky tape.
