Just tried to check us all in on-line and got my first surprise of the trip...  It seems that our first leg (Alaska Airlines to Seattle) isn't an "international carrier" and they said they can't check us in for the international part of our flight, so they can't check us in on-line at all.  No biggy because we have to drop bags, right?  Well, then the agent said that we MAY be forced to reclaim our bags at SEA and then RECHECK them with Delta for our flight to ICN (Seoul).  What fun.  Good news:  We have a 3+ hour layover at SEA anyway, so that would give us something to do.  Flexibility is the key to airpower--and so is showing up early.  I'm going to call the shuttle van people and we may leave our house 15 minutes earlier just in anticipation of additional "surprises" when we all arrive at DEN. ;-)
