If you travel with checked luggage, place most of your liquids there, taking only essential toiletries you need to access on the flight in your carryon. If you travel hand baggage only, be ruthless about what you truly need to take versus what can be bought at your destination.

I’m still surprised at the number of (I’m sorry to say mostly Americans) who are pulled aside at security with what seems like the entire contents of Boots/CVS in their luggage, and proceed to try to litigate an exemption for each one individually with the security staff. That only slows down the process for them and everyone else behind them. If you are pulled over for secondary inspection, don't fight for exemption to the clearly posted rules.

Place your single liquids bag flat in a tray with nothing on top of or under it. Same for any electronics — phone, iPad, laptops, etc.

Remember any liquids you acquire on the journey e.g. business class amenity kits will also need to be discarded or put within your liquids bag.
