I just had the pleasure of learning I have lost my US Airways miles. According to the service center, it seems the deadline has past and no exceptions can be made. February 28th of this year was my line in the sand to recoup the miles. I have not flown US Air for a few years due to a job posting. Now that I am home, I went on to book a flight and found almost 300k in miles expired. US Air claims they sent emails. I have been a member of their FF program since 1987. Do I have any recourse or option other than walking away from this airline? Any advice would be appreciated.
