fekker - also like to add that this is the right place to find support and advice.
There are quite a few people here who bought tickets fully aware that they were mistake fares, but it's obvious that most people who bought tickets didn't, yourself included. I think most people with an interest in this thread will be very keen to find out how your case goes, so do use the valuable resources and insider knowledge from people here, but please also keep us up to date with the response you get from BA.
My personal involvement was that I was made aware of the Dubai tickets you bought, but couldn't replicate the price through BA or an agency I would personally trust, or any other sources so backed away. I knew they were cheap, but thought it was an agency error rather than a BA filing error as I do not thing the pricing was cheap enough to be classified as a 'manifest error'. I suspect we're going to get some very cheap pricing on the route similar to these prices from Royal Brunei over the coming weeks as they will be bypassing the Dubai stopover from LHR towards the end of the year.
