Let me start by saying yelp should offer an option for companies that deserve less than one star. US airways would certainly qualify for less than one star in customer service. I booked a flight on American, but discovered when attempting to check in that the flight was fulfilled through US Airways. Although I booked through American, I could not check in for the flight on the American airlines app. I also could not check in for the flight on the American Airlines website, or the U.S. Air website. When I called US Air for assistance they refused to check me in by phone. They insisted that I had to go to the USAir website and check in. Their offshore customer assistance representatives are extremely condescending to those needing assistance. Hint: if you find yourself in this situation, the record locator that American airlines gives you, is actually what US airways calls a confirmation number. You will not see the phrase record locator on the US airways website. Also, there is no button that says check in on the U.S. Air website. You only see a reference to checking in after you have worked through numerous screens regarding seat selection, etc. At that point, the site announces that you are checked in. The good news is that hopefully by the end of this year the name US Airways will no longer exist.
