My wife and I are travelling out of Zurich in early January. Ideally, we would like to drop off bags in the morning and spend a few hours in Zurich before our late afternoon flight. Does anyone know if they will accept bags at Zurich many hours before the flight? If it matters, I'm a Gold and we will be travelling in ET. If not, we will use left luggage but would be nice to know the bags are already checked-in.

Thanks for insight!
