Not silly at all, because it's not immediately obvious and I'm sure many of them have been wasted.

Like most frequent flyer programs at their elite levels, USAir offers domestic upgrades, which are usable only on domestic flights, only with certain fares, and usually only within a few days of the flight on a space available basis.

On the other hand, SWUs can be used for international as well as domestic travel, with virtually any fares, at any time before the flight, and (it appears) can be used to reserve any available seat. And -- unlike domestic upgrades -- one certificate upgrades your entire flight, no matter how long or how many segments.

In short: They're upgrade certificates on steroids.
