The rules in numbers

- Larger containers that alarm or test positive for certain chemicals may be refused at the checkpoint
- Checked: no size limit
Packing tips
- Take medically necessary liquids out of your bag and tell the officer at the start of screening to avoid a bag search.
- Bring a travel-size bottle in your carry-on and put the full bottle in your checked bag, since peroxide-based solutions are among those that can alarm.
- Pack your lens case empty in the quart bag area so officers see it with the solution.
