Not sure if it's representative, but Mrs Outlaw and I used online check in with luggage on Monday and we were through the BA bag drop and security at LGW N in 15 minutes. Every scanner was open. I noticed they've taken away the Fast Track lanes now too, everyone uses the same lanes as was explained to a couple in front of us.
Even though we were Club it made no difference as we've queued for longer than that when they were open !!
Can't be a bad thing.
