I am looking for one way flights to Tokyo from SEA in early April. I know it's a busy time. I had expected (incorrectly?) That availability would be made each day as the date got closer. However I am not seeing anything available beyond 2/29. Is there something about release in batches that I am unaware of? There are award availability going thru SFO, but of course if I can do a non stop direct flight I would prefer that. Anyone have ideas why direct from SEA isn't available yet? Or when they might be released? Or maybe I should just book the SFO route? If I book and need to change, my understanding is the $12 partner booking fee is non refundable is that correct?
