My wife and I recently had two great flights from Los Angeles to Seoul and from Seoul to Jakarta. The flight attendants were friendly, polite and attentive, and our economy seats had excellent legroom compared to other airlines we've flown. Also, the food and the entertainment were quite enjoyable. I would be happy to fly Asiana Airlines again.
