I believe the British Airways schedules are being updated at the moment. Therefore some schedules are provisional.
If you check the One World Timetable, that can be downloaded online and is updated regularly, you will see that most frequencies have been maintained at Gatwick (at the moment).
I checked for the month of July 2012. Of course changes take time to filter through but the full schedules will become clear in a few weeks time.
Thanks.
