Was offered 35, 000 USairways Frequent Flier Miles to open USAirways Mastercard. Read offer sheet thoroughly and found no mention of annual fee. Also 0% for 6 months on balance transfers. Needed the miles for pending USAirways travel. Currently have an American Airlines Mastercard. They have been a pleasure to use with clearly noted policies.
Checked online and found 3% charge on balance transfers. Reviewed literature sent with the card and no mention of the balance transfer is noted. It was noted on the back of a later mailing (Welcome to Your New US Airways MC), in small print, that a there was a 0% introductory APR on Balance Transfers for the first 6 billing cycles. In that paragraph, it is noted that a Balance Transfer fee applies to all balance transfers. No mention is made of the amount of the fee.
I was able to find the 3% charge in small print in the Cardmember Agreement.
All of this literature was received 2 weeks after I received the card and had already made the balance transfers.
I called and complained as well as emailed Barclay's (the Bank handling the card) immediately and their response was, "too bad". The email is noted below.
