This is the first time I can recall Alaska promoting their first class fares....I call this a promotion rather than a "sale" since all the fares they've listed (at least from PDX) seem to be the "usual" discounted first class fares that are normally available on these routes. From a cents per-EQM standpoint (especially given the current 50% bonus along with the usual class of service bonus), I would say the fares to DFW/DAL are the best deal on the list.
