Last Updated on Mar 5th, 2024 by Ankita Awasthi, Leave a Comment

Amidst the pandemic years, it has been hard for all travelers to keep a check on their travel calendars. But as the traveling restrictions are easing out with time and reduced Covid-19 strain, a passenger may proceed to fly for a valid reason. For passenger safety assurance, the TSA liquid limits have been revised on the carry-on regulations fronts for boarding a flight.
According to the latest TSA updates, the authorities shall allow the passengers to carry hand sanitizer up to 12 ounces while boarding a flight. The Transportation Security Administration (TSA) liquid rules have been updated in the wake of the Covid-19 strain.

TSA Precheck Requirements

TSA liquid rules have been updated and are taking their passenger’s safety pretty seriously as the airport health officials are promoting the regular hand wash while being in the aviation port premises.
The TSA pre-check requirement primarily comprises the quantity of sanitizer that has recently been granted by the authorities. Each passenger must learn that if they are planning to carry sanitizer as carry-on luggage it should not exceed the limit of 12 ounces. The sanitizer can be carried along while flying until further notice. 

The TSA liquid size is comparatively greater than the previous standard liquid allowance as earlier, the TSA liquid rules for carry-on luggage was just about 3.4 ounces. However, the sanitizer being a liquid substance will be screened separately from the other carry-on luggage. So, if a passenger is planning to bring the sanitizer along as the carry-on luggage, they must make sure they have kept it handy which later can be kept aside conveniently.  Also, with the step added to the separate screening, the whole procedure may take longer than usual.

Updated TSA Liquid Limit Regulations

With sanitizer carry-on quantity as an exception, the TSA liquid limits for carry-on luggage are still the same for other liquid or gel items. So, if a passenger is planning to carry a liquid/semi-liquid item as carry-on luggage, it must not exceed the TSA liquid items limit (3.4 ounces or 100 milliliters carried in one quart-size bag). However, the new TSA liquid rule upgrade allows the flyer to tote hand sanitizer (up to 12 ounces) apart from other liquid items.

TSA Precheck Liquids Rule

TSA Precheck Liquids Rule has been quite a popular subject of discussion ever since TSA has revised its liquid rule as carry-on luggage. Well, the TSA precheck liquids rules are pretty simple to follow and could be referred to as given below. Therefore, before you pack up your travel bags, you must know the details and guidelines briefly and proceed accordingly. 

  1. The TSA liquid rule for carry-on baggage limit has been exceeded to only sanitizers and not all the liquids that a passenger must be carrying.
  2. Apart from the 12 ounces of sanitizer, a passenger may carry  3.4 ounces of liquid products like gels, creams, pastes, and aerosol as their carry-on luggage. One of the best tips that can be recommended for such a case is the passenger may transfer their other essential products into travel-size bottles instead of their full-size packaging. 
  3. Except for the sanitizer, every other liquid/gel item must fit in the given limit and a quart-size baggie. 
  4. In case the passenger is unable to fit in the liquid/gel items in the given quart-size baggie or within the given quantity frame, MTI suggests shifting the passenger’s extra liquid items in their checked luggage. 
  5. Needless to say, the liquid carrying restrictions cover not only the cosmetic items but also the food and beverages (if carried along). However, the TSA checkpoints have a pretty grey area for the food item that can be allowed onboard or not. 
  6. Passengers carrying along with breast milk, baby formula, or any doctor-prescribed gels, creams, or liquid medications are duly excused from these TSA liquid rule limitations.

How To Renew TSA Precheck

The TSA precheck renewal is a very simplified procedure. All a passenger has to do is fill in the essential details and submit the application online for remote submission. In case a person wishes to complete the application and submit it in person, they can proceed by visiting an enrollment centre. The process should be initiated six months before the expiration date of the KTN (Known Traveler Number). If delayed, the process can be carried through up to one year from the expiry date. 

Note: There can be exceptions for a few flyers as they would not be able to proceed with the procedure online. These passengers may have to provide updated data or fingerprints at the enrollment centre to proceed further. Also, if a passenger is not eligible for online form submission, they’ll receive an on-screen automated pop-up notification for the same. 

TSA approved Baggage Dimensions

The airport authorities duly follow the Transportation Security Administration and its regulations. As a matter of course, the baggage dimension and weight limit for both carry-on luggage and checked luggage have been established in advance by the TSA. However, the measurement for each category varies and has been locked on the basis of its requirements.

TSA Carry On Liquid Size

According to the TSA dimension restrictions, a carry-on luggage size should not exceed the dimensions of 22x14x9 inches. The dimensions must be inclusive of the handle, strolling handle, wheels, and extra accessories on the bag. Although the airport authorities strictly follow the dimension restriction, there is no weight limit for the carry-on baggage. 

The passengers carrying personal items except for the carry-on luggage (TSA carry-on luggage size limit) must not exceed its dimension more than 18x14x8 inches. Personal items are not something every passenger carries as it is referred to the items like a purse, laptop, laptop bag, mini-backpack, camera, camera case, etc. However, the passengers must keep in mind that the personal item should be within the given dimension. It can only be held under the designated seat on board(if the carry-on luggage storage area is already occupied).

TSA Liquids Checked Baggage Size

The TSA liquid rules for checked baggage dimensions are not mentioned as such. However, if the liquid item limits more than 3.4 ounces or is kept in a bottle that is greater than the given dimension, it must be transferred to the checked luggage. TSA approved liquid rules for checked baggage size is a product that fits within the given checked baggage dimensions that need to be carried or is larger than the TSA-approved carry-on liquid item size. 

Speaking of the luggage dimension, the TSA has a pre-established norm and regulation for the same. The checked luggage combined dimension can be exceeded up to 107 inches, and individual check luggage dimension can be stretched up to 27”x21”x14” but not more than that. Also, the passenger must keep in mind that the linear dimension of each piece must be within 62 inches. As far as the weight limitations are concerned, each checked luggage piece must not exceed the 23 Kgs weight limit.
