If you are based in SEA like your profile states then you will have to get to SLC (Delta), DEN (United) or OAK (Allegiant), right now you can purchase a ticket on Allegiant for $48 on specific dates--they only fly OAK to IDA on Sundays and Thursdays. Might be worth the little extra $$ for confirmed seat as long as you think you can get to OAK on AA (looks like you would have to go via PHX).
Will you ZED from SEA or get to SLC/DEN/OAK on AA then ZED?
Anyways, once it gets closer just ask for load information and someone will help. Above just gives options
