As mentioned, the KE lounge and J class food offerings are underwhelming, and I also did not think there was enough food served for the length of the flight.

However, the benefits of the non-stop outweigh these deficiencies. I flew this route on an almost monthly basis in 2013/2014 from the PHL/NYC area, and because ICN is a morning flight from DFW, no matter how early your connecting flight to DFW, it makes for a tight connection. I have missed the ICN connection a handful of times due to delays from de-icing, going around storms enroute to DFW, and once the flight to DFW was delayed from increased flight times due to strong headwinds.

And if you will be flying this route a lot, you will rapidly get bored of the limited selection of entertainment on the AA 772 by the second or third flight. KE entertainment is much better.
