This may have been covered. I apologize if it has. 1. Does over the land segment (open jaw) count towards miles traveled? 2. Is US Air considered a non AA carrier currently? (i doubt this, but just confirming). 3. Is travel required on AA itself? If so, does traveling on US Air fulfull this rule (tied w question 2)?

What's the best site (in general, not OW specific) to look at flight numbers and transitting cities (i.e., which flights continue to other cities w same flight numbers)?

Thanks in advance.
