Traveling carry-on only might seem restrictive and difficult to do, but I believe NOT checking luggage provides me with more freedom. Whether you’re trying to avoid checked bag fees, you’re worried about the airlines losing your luggage, or you just want to travel lighter, packing carry-on only is something you can easily do too. I’ll show you how!
Aside from the amount of stuff you put in your bag, packing liquids might be the biggest hurdle to traveling with only carry-on luggage. But it’s a problem with solutions if you really don’t want to check your luggage.
Here’s how to make flying with liquids easier next time you travel.
How much liquid can you bring on a plane?
The first thing you have to know is how much liquid you can take on a plane.
The TSA carry on liquid allowance is 3.4 ounces (100ml) per bottle, and all bottles must fit into a 1 quart (1 liter) clear zip top bag. And you’re only allowed to have one liquids bag per passenger.
This means your 6 ounce tube of toothpaste will be confiscated, even if it’s almost empty. And keep in mind that virtually every country in the world now follows this rule for bringing liquids on planes.
It’s also important to know what qualifies as a liquid. Anything that could be considered a liquid, gel, cream, or paste counts.
That means make-up like mascara needs to go in your liquids bag. Peanut butter is considered a liquid. Gift items like snow globes have liquid in them.
All of these things must be counted when you’re trying to determine how many ounces you can carry on a plane.
The good news is you are allowed to bring a full size empty bottle through security. This means you can fill up on water once you get through security instead of having to buy overpriced water at the airport.
The liquid allowance on flights shouldn’t stop you from staying hydrated.

Stocking up on travel size liquids
Go to your local Target, pharmacy, or any other store that sells toiletries.
They should have travel size liquid options or trial sizes of certain products. You can find all sorts of things in travel sizes, which is perfect for flying carry-on only.
Occasionally they have things that are small but still over the liquid allowance (100ml or 3.4 ounces per container) so make sure you check the labels.
Buy yourself some toothpaste, shampoo, and anything else you use regularly. Usually you can find refillable containers too, but again, check the sizes.
You can also purchase travel-friendly and refillable bottles for your toiletries. That way there’s less wasteful packaging to throw away, and it’s easier to take the same products you use every day at home.
GoToob makes some really great bottles in a variety of travel sizes, and they’re made of high quality material that will last. Check them out on Amazon here.
Flying with liquids: How much do you really need?
Don’t worry about having enough liquids to get through your trip. I wear contacts, and a 60ml (size found at Target) bottle of contact solution lasts me around 5-6 days. Even if I brought two bottles, that wouldn’t last for a two week trip.
But I know I can buy some on the road, which saves me space and allows me to stay within the carry on liquid limit and fly carry on only.
In the US you can find contact solution almost everywhere, from pharmacies to grocery stores.
Outside of the US it’s a little different, but you just have to know what to look for. In most other countries, you might need to look for an optical boutique, or something similar to a US drug store that just doesn’t have the pharmacy/prescription section.
You might not need as much as you think you do. Test out your travel sized liquids ahead of time. How much shampoo or toothpaste do you use in one week?
My travel shampoo bottle is one ounce (about 30ml) and even after a two week trip, I still had a little left in the bottle. Recently I tracked how much shampoo I used, and that one ounce bottle lasted me 17 shampoos!

Consider packing non-liquid alternatives. Solid toiletries won’t count against your liquids limit.
I usually don’t travel with shower gel because it’s just one more liquid taking up space in that small bag. Instead I use the hotel’s soap or shower gel, and I bring a bar of soap as a back-up in case I stay somewhere that doesn’t provide toiletries.
Dry shampoos and shampoo bars are available too, but you might want to try them out ahead of time to see how they work with your hair.
In fact, I now use them at home too because I think they’re so great. They have different varieties for different hair types, so look for the one that’s right for you.
Instead of worrying about your favorite perfume getting confiscated, pack one that won’t count against the amount of liquid allowed on plane. Try one of these great solid perfume sticks.
You can even get solid toothpaste tabs as an alternative to normal toothpaste.
I also tried solid sunscreen and solid bug repellent recently, and they worked great.
The sunscreen was sort of like rolling deodorant all over yourself. You have to be a little more careful to make sure you don’t miss spots since you won’t be rubbing on a white lotion, but it worked just as well as normal sunscreen to keep me from burning.
The bug repellent kept those pesky mosquitoes away from me just like bug spray. I’m one of those people mosquitoes find from miles away, and I was happy with this.
Medical exceptions to the carry on liquids allowance
Look for any exceptions to the TSA (or the agency for whatever country you’re traveling in) regulations about packing carry on liquids.
In the US, and many other countries, liquid medications are exempt from the airplane liquid allowance, which lets you to bring more in your carry-on luggage.
But the rules vary by country, so do some research. What one country considers medically necessary, might not be the same in another country. When in doubt, have a note from your doctor.
If you want to pack light with liquids, cut back on the amount you bring on a plane and reevaluate the amount you actually use per day. Buy toiletries as you travel and consider non-liquid alternatives. Don’t let the carry on liquids allowance hold you back from traveling carry on only!
