I recently cashed in some American AAdvantage miles for a Business Class transatlantic award trip with Air Berlin. Having called AB to get my booking reference at 10p per minute, I logged in to their web site to select my seat.
Having chosen my preferred seat I was offered the chance for pay £0 for the privilege:
And the web site wouldn’t continue until I paid.
So I entered the credit card number and ‘paid’ and then completed the booking. Of course no charge has appeared on my Amex.
It just seems a little weird!
