"The commute from SEA to ANC is not too bad,"

My crash pad room-mate was trying to commute on that route.. took him all day to get to ANC. He started on a 8 or 9 AM flight and didn't get out till 9PM due to fuel restrictions and standbys.
I will agree with a previous poster... its a must to get up a day early and have time for rest/backups.

welcome and good luck.
