I can even cancel his ticket, change seats, order a special meal etc for a ticket that is not mine! This is a serious data breach…
That would suggest that your email address is somehow in that random stranger's booking(s) - and if you get notifications for more than one booking for the same stranger, then your email is in one of their profiles (either BAEC or that person's profile with their travel agent). That, or they keep typing the wrong email every time they make a booking...
Per https://www.britishairways.com/en-us...privacy-policy you can report the suspected data breach/confusion to [email protected] - if you have more than one example to give all the better - will help them track down how your email is in these PNRs/profiles. Avoid mentioning that you've accessed MMB for someone else's booking - they'll understand the implication! 
(although if their bkgs are appearing in your app without you doing anything, do mention that!)
