I got that 30 or 40k barclays USair mastercard....supposedly its churnable? its been a year, sitting on 34k miles. want to keep them I called to cancel the card cuz the last thing i need is an annual fee and the dude CSR said that I forfeit any of the bonus miles earned from the card....is this possible? Even when they got spent on flights last summer? can they call USair and deduct miles from my account?
