Bad Usability: US Airways Flight Status

So I go online yesterday to check on the status of a friend's flight on US Airways' website. We're picking him up, and we want to see whether the flight is early, on time, or late, to adjust when we leave our place to head to the airport.

I click on "flight status" and I get this simple form:


I enter the flight number, and I click on Retrieve. Then, I get this message:

We're sorry, but we were unable to complete your request.
Please enter a departure city in the 'From' field.

Well, I don't know his departure city. In fact, this is the second leg of his journey, so even if I knew where he was flying out of, I didn't necessarily know his connecting city.

What gives? US Air has the schedule for this flight number. Why doesn't it show me the full itinerary and let me figure out which portion I'm interested in?

Fortunately, Yahoo Travel both had this information and was willing to share it with me. Thumbs down, US Air. You took an obvious task and made it harder than it had to be.
