3 oz. if you go to target, they have small shampoos, conditioners, deodorants, lotions, exc. otherwise, you could buy a big bottle, then at walmart or walgreens they sell small 2 oz or 3 oz containers, that you can pour some shampoo and stuff into the containers, then put the rest in your actual luggage. that works very well in the rare case that your luggage gets to you a day or 2 later.





you can get as many 1 2 or 3 oz bottles you can into a QUART size ZIP-TOP bag. it must be able to be zipped shut! when you get to security, put your carry on on the belt, take out your one quart sized bag with your liquids in less than 3 oz containers, and they will scan that seperete.

you’re packing for a trip and realize you don’t have a 3 oz. or less tube or bottle of toothpaste, hair gel, shampoo, etc. on hand, these small (2 oz.) bottles are a terrific solution.





they’re a handy way to carry less than 3 oz. of gels, shampoos, and the like.





Also, if you want to bring your cologne along but are worried about spillage OR the bottle’s too large, transfer a small quantity to a cologne or perfume sample size bottle








Doing so from a spray bottle into a sample bottle is not an activity to which I would apply the word “precise,” but it can be done. Have some running water nearby and wear glasses or safety goggles.








I usually pack the sample size bottle in a small ziploc bag inside my quart size ziploc bag just in case any seepage occurs.
Its not the ariline that decides, its the governing body of the aviation industry, so its the same for every flight, no matter where or who is flying.
3-1-1 rule. 3 ounces, 1 quart bag, 1 per person. Meaning, however many 3 ounce bottles you can fit in a quart bag.
