On a recent trip to London we used our Visa card to call Heathrow airport from downtown London. Our call to confirm our next day departure was nine minutes long. We are now back in Canada and just received the charges on our visa statement. In Canadian $$$, it was a whooping "$49.83" There has to be a better way or least expensive way to make a call in London area! We do not have an international cell phone so that option is out. Any recomendations would be appreciated before we make another trip across the pond.
