Thanks, but I am looking at other airports and I have a certified allergy to junk emails, worse to junk SMSs.

cme17 and JamieT, thanks, good to know about being notified of cancellations, but it's not much use for picking a person up at the (non-LHR) airport tomorrow and for knowing if our outbound flight later this week will be on time (and, even better, the aircraft as it's coming it)

This site will alert only if you pay for the premium version of the service, like www.tripit.com. Without paying you are not alerted, and if I'm using an app/website to look FLIFO up, it might as well be BA's for a better chance at getting accurate info (who knows where do these sites, like flightstats, source their info and how often they update it).

Thanks all for the replies and confirming that I didn't miss anything, but BA has some work to do in this area!
