Don't be dissapointed the "majors" all leave at 1:00am. I fly this route often and unless you are looking for status tier miles alaska is a partner of many of the majors (AA,CO,NWA and a few more HP maybe?) and you can earn miles with your preferred carrier. There are two considerations 1)price 2) miles. As far as price, as they say in brooklyn, "foget about it". There is no discounting on this route. As for miles the large number of parters (of alaska) is a good thing.
