Award availability using DL SkyMiles on ATL-ICN used to suck. ATL fliers routinely had to route through other gateways, such as IAD and ORD. Recently, possibly in relation to introduction of the nighttime ATL flight, award availability has improved tremendously. I've now got a couple of awards ex-ATL on the daytime flights KE 35/36. For those of us in the southeast, that's one of the best routes to SouthEast Asia. And award availability on intra-Asia routes has always been good, as long as you avoid blackout dates. Plus, taxes and surcharges on KE when redeeming SkyMiles are very reasonable, around $60-- as compared to $300 on MU and $500 on MH to SouthEast Asia. All things considered, leaving aside the blackout dates problem, KE's a great deal when redeeming miles, and the service (both hard and soft products) is now excellent.
