Got an email from BA overnight, informing me that my late October flight on BA001 now departs LCY at 0950 instead of 1250.

Had a quick look at other timings out of curiosity. BA003 is still at 1600. The return flights leave JFK at 1955 and 2255 instead of the current 1910 and 2150.

If this has to do with Shannon, surely the later flight should have been moved earlier too? And once moving it earlier, why not have it as early as possible to allow most of a working day in NYC? The inbound lands LCY at 0715, surely could be turned around in an hour... similarly why not make BA003 a little later if Shannon is still open, to allow a fuller day of work in London?
