Really it seems long for some but the outgoing flight arrives late at night(10:15) and the returning flight leaves really early(07:15) so you basically get 8 days if you look at it that way
Allegiant doesn't have as many flights but the price is right. Looks like they have flights going out on Wednesdays and Thursdays with returning flights on Sundays and Wednesdays.
Wondering how those rates stack up to the competition? Cheapest I can find from Seattle is $754 for April 10th-17th.
I have never flown Allegiant before but it seems worth looking at for your next trip. They fly out of some smaller cities. For us NW folks up here it's Bellingham, Spokane, and Eugene, OR.
I wouldn't expect to get the same service as a major airline, but if the price is #1 factor, they may be everyone if you are flexible.
