"Moscow, first-class return, pounds 810" - advertisement in Travel Weekly

How can this be? The best that British Airways can offer between London and the Russian capital is a club-class fare costing nearly pounds 1,400. But this advertisement promises "The sophistication of Airbus. Inflight cuisine by Marriott. Exclusive departure lounges". The solution is at the foot of the ad from IMS Travel (0171-224 4678), where the familiar winged hammer and sickle announces that this is, of course, a flight on Aeroflot.
