I've never flown Delta nor have I ever had any KE miles, but right now Delta looks like the best way to fly to Hawaii next year. I know KE miles can be used to book "saver" Delta flights, but since Delta doesn't have a firm award chart, I'm not clear which flights can be booked with KE and which can't. For example, the lowest award cost for LAX-HNL is 22.5K DL miles, but on my particular dates, it's 27.5K departure and 37.5K return. Does this mean KE miles won't help me here?
