## Redeeming Rewards

Spend miles to move a shipment up the queue: a priority upgrade costs 2,000 miles and is charged when you change the shipment's priority.

> **Tip: Double Miles on Warp Days**
> Every shipment booked with `express-warp` delivery on the first day of a galactic quarter earns double Stellar Miles.

Try a priority upgrade in the sandbox:
