While I know this may not help most people coming to the UT Gathering (unless you are coming a few days early and from the West), Alaska Airlines is offering free tickets to Snowbasin. You have to fly Mon-Wed and tickets are valid Tue-Thu and you have to fly "via Boise, Los Angeles, Portland, San Diego, San Francisco, San Jose, and Seattle."
From
https://www.snowbasin.com/about/partners/alaska-airlines-ski-free/
"Fly Alaska Airlines to Salt Lake City International airport on any of the direct flights from seven different cities between Monday and Wednesday and register at SkiOgden.com for your free lift ticket to Snowbasin Resort."
"Visit
www.visitogden.com/ski-ogden/snowbasin-ski-free-promotion to register for the ski free promotion after booking your Alaska Airlines flight. Must present your boarding pass, Visit Ogden confirmation email and photo ID at Snowbasin Resort within 24 hours of arrival for a free single day lift ticket. Valid 12/4/17-12/15/17, 1/2/18- 4/8/18. Must fly Monday - Wednesday and redeem ticket for same day use on Tuesday - Thursday, day following flight."
The "redeem ticket for same day use on Tuesday - Thursday, day following flight" is confusing as it seems like it should say next day and what about if you can arrive early enough to ski Snowbasin the day you arrive as I did when Park City had a similar deal with any airline.
