Packing tips
- Switching to a solid stick is the easiest way to free up room in your quart bag.
- Gel and clear-gel 'sticks' that are soft or squeezable count as gels, so keep them 3.4 oz or under in a carry-on.
- Keep the original cap on spray cans in checked bags; a loose nozzle can discharge under pressure from other items.
