The Canyons:
You simply take ANY airline ID to the Delta Credit Union in SLC airport (next to security at the top of C) and they will sell you as many tickets as you need for $50.00. It's a huge savings. The process has been confirmed with the sales manager, Donna Sheeran, at the Canyons.
Snowbird:
Scott Appleman, Group Sales Manager at Snowbird told me that we get a ticket for $50.00 with our airline ID right at the ticket window. (If anyone knows if this extends to family and guests, please let the Webmaster know.)
