So this is my first post here (I've been stalking the forum for a little while) so apologies if this isn't done right. This one is a true easy-peasy milk run.
Anyhow, Alaska is currently offering double elite qualifying miles on all of their routes to Salt Lake City. They are also offering 5,000 bonus miles if you fly round trip through a "West Coast ski destination" twice by March 31st (must register your FF number on the requisite sites which I'll put below) before flying - of which Salt Lake City is one of those destinations.
Just booked SEA>SLC>SEA>SLC starting at 7 am and finishing at 6:30 for February 8th, $99 each way.
$99x4=$396
687 miles x 2 each way = 5,496 miles
5,000 non-status bonus miles for 2 round trips = 5,000 miles
As an added bonus, you'll be home for dinner.
