not showing flight

I was trying to track my husbands flight and us airways shows his plane has departed about 20 minutes ago. It’s not showing any activity from his flight when I try to track it. Is there a problem?

What’s his flight # and what are the dep and arr airports? It may be under a different number here or it may be a code share. You can also enter the city pairs to the left where it says Don’t know the flight number?

that flight might also show up as AWE.
