In my experience the liquid checks are now pretty thorough for transit pax who are required to clear security. Electronics and liquids now all need to be removed from hand luggage for screening.
I had a 150ml aerosol confiscated in DOH last week that I'd just bought prior to my first flight - no big deal - but I wouldn't like to lose a whole bottle of vodka!!
Find myself missing the days when transit security was only really for show
