Flights have been going around Pakistan airspace for quite some time now - and yet the schedules for BA are still as before.

All that happens is you get a notification in the morning the flight is 1hr delayed leaving (due to late arrival), and a further hour or so delayed returning.

This happened on my DEL->LHR flight, and many people were clearly missing connections that BA would have been able to avoid doing many weeks, if not months ago.
