As others have noted, you will not be upgraded, even to Premium. There are usually some seats available at the "back of the bus" that are designated as Saver, the seat is light blue and has an "S" on it. Those can be selected at the time of booking, otherwise you will show on the "awaiting seats" list, which you can see at 24 hours prior to departure, and a seat will be assigned at the gate. The "awaiting seats" list is not strickly Saver passengers but will make up the majority of the list. Non-rev passengers and standby will also be present.

As a 75K, you will still get priority boarding, full EQM, your Elite bonus RDM & a complimentary beverage.
Not only are you not eligible for upgrades, the most punative characteristic of Saver is that the fare cannot be changed or canceled. If you are outside of 24 hours before departure, you can cancel for a refund within 24 hours of purchase, otherwise your money has flown, whether or not you fly with it.
