Southwest · with a stop · 5h 5m
The catch: The Southwest fare has one stop and takes 5h 5m, November usually brings drizzle and a rain day, and resort fees and a checked bag aren't in the total.
Worth it if a stop and cool, gray November days don't bother you; skip it if you'd rather pay $424 for two for the 2h 14m Alaska nonstop.
