Eurynom0s I just read through the entire thread again and my interpretation is that your top priority is to get to Boston as soon as possible and with as much certainty as possible. If that is the case then I think I would take the 11:32 AM flight you mentioned. That gives you a time buffer, to include one backup flight to SEA if things really go crazy. Hopefully everything goes without a hitch, and if so, then you can go to one or more of the lounges (there are plenty in SEA), assuming you have access to the Alaska Lounges, Priority Pass, and/or Amex.
