+1 and wise words there.

Good luck Lunamoth, keep checking daily and even more frequently especially nearer to the date for all the time that it takes.

SEA is a busy Business route so there may well be last minute changes/cancellations, or alternatively in the 'worst case' scenario there maybe even nothing at all.

Please do post back as I think it's fair to say that finding out how stories end is appreciated on here.

Not sure what you are prepared to pay etc. but you may be offered a Pro Active Upgrade (POUG) to First Class in Manage my Booking. It's 'usually' about £499 or thereabouts but there is no guarantee you will receive any such offer.

You can also ask if there are any paid offers on the day at the Airport (AUP).

Personally CW is fine for an overnighter but some food for thought especially on the way back if indeed such an offer were to pop up.
