EDIT: British Airways has decided not to honour these tickets. You will see via Manage My Booking that your flight is cancelled. No-one has yet received an explanatory email from BA and there is no timetable yet for payment refunds.
It seems that someone at British Airways has misfiled some fares out of Germany.
First Class to Kuala Lumpur out of any German airport is pricing at £795 return. Sydney is £1,335 return – in First.
I am not at my desk so can’t write much. Go to this Flyertalk thread for details – http://www.flyertalk.com/forum/premium-fare-deals/1704005-ba-cx-mh-f-fra-kul-route-via-hkg-sin-1-300-a.html
I got it to price so it is working. Whether BA will cancel your ticket or not is a different question ….. they may well do. (EDIT: yes, they did!)
I fully expect this fare to be withdrawn within 1 hour.
