A non-revenue ferry flight (aka positioning flight) will normally carry a BA9xxxP flight number and use BAW9xxx for the flightplan/callsign. Interestingly, there was also a BA294F yesterday - a B77W landing at LHR just after 5pm, having been sent to Shannon (as BA9158P) but presumably not able to accommodate all the stranded passengers so the lucky(?) few left over would have been rattling around on today's 747.
Incidentally Heathrow's Arrivals web page is still showing yesterday's BA294 as "On Time 07:45".
