There still seems to be a lot of confusion about what can, and can't, be taken through security and onboard the aircraft. We want to try and make your trip through the lines a little quicker.
EACH passenger is limited to ONE zip-loc style baggie, QUART-sized, in which you can place as many "Comfortably-fitting" (read easy to see) items of MOST* liquid or gel products, as long as EACH item is in a container that is 3 OUNCES, or less, in size. (*NO liquid or gel product can be of a flammable nature.)
You CAN NOT have a 6-ounce bottle that is half full. You CAN NOT have a 10-ounce tube of toothpaste or hair gel that is three-quarters empty. You CAN NOT have a 3.5-ounce bottle of mouthwash (and just try to find one of those at 3-ounces, or smaller).
Don't fill this limited space with everything you normally keep in your toiletry kit (hairbrush, floss, toothbrush, etc.). Put those items in your usual toiletry bag. Your zip-loc baggie of liquids/gels must be OUT of your carry-on baggage and sent through the screening machine separately.
So, what can you do if you need liquids or gels in larger quantities?
- You can place larger quantities in checked luggage.
- You can purchase larger-size products on the other side of security (but remember, you won't be able to bring them back through security on your return flight).
- You can transfer products to smaller, travel size bottles. Just be certain that they are marked, or are very obviously, 3-ounces or less.
- Check with your hotel to see what they already provide (many have expanded way beyond just shampoo and conditioner) which might allow you to bring the specific items you need that aren't already available, gratis, from your hotel.
- Consider substitute products. Liquid nail polish remover can be replaced with "acceptable" pads that are saturated with the product. The same goes for hand sanitizer cloths vs. a bottle of liquid hand sanitizer. We even hear that tooth polishing "powder" is making a bit of a comeback.
There are exceptions, of course. Certain medications (prescription or over-the-counter) may be acceptable in larger quantities. Breast milk, baby-food, or required hydrating products may be acceptable in larger quantities. Water, sports-drinks and other non-essential beverages must be consumed before passing through security (you can, however, purchase these items on the boarding side of security and take them onboard the aircraft).
