I took out the UK Citibank AA card a few months ago.
Anyone considering it should know that you can't pay your bill over the 'phone each month like every other credit card I've ever had.
Oh no, you have to post them a cheque which will take seven days to clear. Or you can pay cash at a branch - but that still takes 4 days to clear. 4 days! For cash!
Maybe I'm just grumpy 'cos I had to FedEx them a cheque the other week, during an unscheduled trip to the USA
