That US airways flight is on the America West operated aircraft, we've flown that route and being an over night job it aint bad.
One tip, 30 hrs before the flight you can upgrade to 1st class for $150 per person subject to availability. We got the upgrade and it was worth it for the night flight, a wider & more comfy seat was welcome. Of course domestic first in the US is no great shakes though

As posted by mitchja you can use BMI miles for a redemption on this flight, not sure I'd burn the miles though as you can usually pick up the flights pretty cheaply.
