I couldn't find such an option anywhere on my menus, but I googled it, and here is the direct link:
www.britishairways.com/travel/my-flight-path/public/en_gb
For me, it displays my flights all the way back to 1991 (
!!)
But, as it only displays the flights associated with one's BAEC number, it does not include any of the flights I've taken in recent years, as I always credit to my American Airlines AAdvantage account now.
