US Airways is GREAT to jumpseat on. Just remember to not bring up the question about the senority list merger with America West and US Air. There is a non-rev # of 1 (800) 325-9999. Just listen to the prompts. Some agents get all bent out of shape if you don't list for non-rev listing. If you didn't list just tell the agent you were on hold for a very long time. Also, bring treats, ie.. candy, cookies for the F/A's and it make them happy. I actually had a Captain get on the PA and thank me for his favorite candies that I gave the crew. Good luck
