Blum said Provo is tough to get there. I know basically nothing about the logistics of it. How far is the stadium from the airport?
Unless you drove out there.
It's really not that bad, IMO. If you fly into SLC (which I would recommend) you can take public transportation (UTA Red Line then transfer to the Frontrunner train) to get to Provo. I would recommend getting a rental car though, especially if you want to drive up into the mountains and enjoy the beautiful scenery.
From the SLC airport it's about a 45-60 min drive (depending on I-15 traffic). There is a small airport in Provo that some of the budget airlines (Allegiant, Frontier, etc.) fly into, but I think there are only 4 gates and options are pretty limited.
For all my friends coming in for the game, I'm telling them to fly into SLC, stay in SLC, and go down to Provo just for the game (either in their own vehicle or via public transit). That's mostly because I know they are going to want to drink, go to restaurants/breweries, etc. and there are limited options for that in Provo. The whole Wasatch front is super beautiful, honestly you can't really go wrong staying anywhere along it. If you've never been, you'd be amazed how close the mountains are compared to a Denver, Seattle, etc.
