How much liquid is in carry-on Delta?

To answer the question, the maximum amount of liquids allowed in a carryon for a Delta flight:

As is usual with any airline company, one of the most frequently asked questions concerning Delta flights is, “How much liquid can I carry in my hand luggage? Considering the fresh and stringent measures put in place by the TSA concerning fluids, gels, aerosols, and pastes, it is crucial to have quite a clear understanding of what is acceptable to carry in any Delta flight. This guide will indicate the currently allowed liquids that one can carry and the requirements during security checks in Delta.

TSA Regulation of Liquids in the Aircraft: The 311 Rule

First, one needs to clarify what rules the TSA has regarding liquids in carry-on luggage. The TSA has what is known as the 311 rule: 

  • Bottles that range in size to 3 ounces
  • One clear plastic Ziploc type bag not exceeding one quart size.
  • The amount of luggage that is allowed per passenger is one bag.

This rule is for each person to carry what is allowed on the plane in terms of liquids, gels, aerosols, creams, and pastes in containers that are not more than 3. 4 ounces or 100ml in size. All of these tiny packages have to be contained in a single clear plastic ziptop bag that does not exceed one quart in size. Liquids, aerosols, and gels are allowed in limited quantity as long as they are carried by a passenger in a single bag. This regulation applies to all hand baggage regardless of its nature such as purses, briefcases, backpacks, etc The rule of thumb is that anything above 3. 4oz has to be placed in the check-in luggage.

So if and when you are packing liquids that you intend to take on board a Delta flight in your carry-on luggage, ensure that each of the containers meets that 3411 regulation. Some examples of small items that would fall under the baggage allowance would be a small bottle of shampoo, toothpaste, face wash, makeup, and hand sanitizers. Just make sure that your liquids, gels, or pastes are in containers of 3oz or less, and they all fit in the quart bag, then you are good to go with Delta carryons according to TSA regulations.

Some of the things that often break the Liquids Rule include

However, the TSA has some exclusions for the 311 rule of carrying liquids and the one named it was: The following liquid items do NOT need to fit in your quart bag: 

  • If a person is traveling with a baby, then he/she should pack baby formula/milk.
  • Liquids, tablets, or capsules with your name on the package or a name that is similar to your ticket.
  • Contact solution, size under 32 ounce
  • Liquid medications above 3oz that are in a sealed container and have a note from the doctor

So if one has to carry an item that has been mentioned in the above list, then it should meet the rules of TSA for that particular category. Its contents should bear the passenger's name to match the prescription; contact solution cannot exceed 32 oz;…Please note that if a liquid qualifies based on an exemption as listed in the categories above, you may pack it separately from the quart bag.

Moreover, free of charge are also the empty reusable liquid containers like water bottles, and tea tumblers, etc., however, they should be empty and free of any liquid when passing through the security checkpoint. Any containers with liquid in them would also fall under the rule bearing the 311 proportions.

Packing Tips Concerning Delta/CarryOn Liquids

Here are some useful tips for smoothly getting your liquids through TSA screening on your next Delta flight:

  • Put all containers in sealable plastic bags: This reduces permeability in your bag and eases removal during security checks. Large bags or baggies used in large quantities can be replaced by several small ones.
  • Place liquids in an easy-to-access pocket: To ensure quicker and easier inspections, make sure to store your quart bag and liquid exemptions at the top of the outer compartments of your bag and not in the interior sections.
  • Avoid overstuffing your quart bag: As much as they are full they become easily breakable. It would be ideal to leave some space for easier inspection access by TSA but not too much to allow security to breach easily.
  • Separate medication exemptions clearly: Do not mix prescription liquids or gels with other liquids in a nontransparent quart bag as these should be in differently colored bags or pouches.
  • Avoid unfamiliar brands: TSA is more likely to pay attention to more unfamiliar brands or labels they don't often encounter, so avoid using unfamiliar regional brands or well-known national brands they recognize.
  • Allow extra time at security: Liquid inspections may take relatively more time as compared to other forms of inspections; therefore, you should arrive at the airport relatively early enough before your flight time.

Penalty for violation: What happens if you violate the rules?

TSA rules do not allow liquids and gels that exceed a certain amount to be transported thus, if you try to take those items, they will be seized at the checkpoint. TSA agents will take away the containers that are prohibited in a carry-on and will not let them be taken on board.

Next time you fly Delta, do not go naked without packing your expensive shampoos or lotions in compliance with their liquid rules. It is always advisable to consult your agent because some of them may allow you to check the banned items at the gate, but this is, however, dependent on the agent's policy.

The only way to avoid such a problem is to pack properly and with the right things to avoid losing liquids. Don't forget their 311-quart bag rule and the other related exceptions before going to the airport to catch a Delta trip.
