I think I can answer the imputed income question. Even if AA doesn't charge for the flight, the IRS sees that as a taxable benefit. And it would be a liability for the employee. So, let's say your flights were given a value of $300. Your aunt didn't suddenly earn $300 by you flying around, but as far as the IRS is concerned, she may as well have. So, say her tax rate was 25%. That would be $75 that she would be taxed on. But when she's retired... I'm a little less sure how that works. Probably worth asking higher powers. But it would be on her if anything so be prepared to write a check. I'd be careful here! While nowhere near full fare, it can add up!
