When I worked on ground we were told to specifically ask about certain items, including but not limited to "aerosols, Zippo lighters and batteries"
I've noticed that the 'two questions' seem to have disappeared from the check-in routine. Not sure if this is because I'm usually on staff tickets (bit worrying, some are dumb as doornails and wouldn't have a clue/care about Li-Io batteries) or because there's no longer a requirement to verbalise the questions due to online/kiosk check-in and/or signage at the airport?
