My plane was grounded due to mechanical issues, and I had to spend 20 hours in the airport. Did I receive a food voucher? No. Even after requesting one, the US airways help desk stated that although they used to offer this, the policy has changed.

Nevertheless, I was given a $200 voucher for a future flight due to the massive delays. This was a good thing.

However, when I called to make the reservation with the voucher, it was 1 hr beyond the 1 year expiration date... literally just one hour. The reservation agent told me that she was locked out of the system due to the expired voucher and could not process it. Who can help?... She advised that I contact customer service, and does customer service have a phone number? No, they do not talk to people. They can only be reached via the automated contact form on the site.

So, I contacted them via the form. Three days later I received an email back stating that my voucher would not be honored even though I was only one hour away from it still being valid when I called to make my reservation.

I may still attempt to contact the US Airways corporate office, as the above contact info is apparent for the corporate office department in Phoenix, AZ, (800) 428-4322 ... but I'm not expecting much. I'll change this review if I'm treated like a human being rather than a number.

A company this large refuses to speak with its customers ... as a matter of policy. Wow.

Once a recurring customer, now ... will never fly with them again.
