In case anyone is interested, at least as of 14/8 the current brouhaha meant that the Early Check In (night-before) service at LGW was unavailable. I was overnighting there anyway, so no biggie, but if your plans rely on using it, best to check by 'phone as on 14/8 the website gave no indication that it was suspended (well, there's a shock - ba.com didn't have full and current info!)
