Southwest Airlines Liquid Rules for Hand Baggage

Southwest adheres to Transportation Security Administration (TSA) rules for carrying liquids, gels, and aerosols on flights. Travelers can carry one quart-sized container of liquids, aerosols, gels, creams, and pastes in the cabin baggage. The items should be kept separately from the hand luggage to make the screening easier. Every liquid, gel, or aerosol should be packed in a 3.4-ounce (100 ml) or smaller container. Containers larger than 100 ml should be packed in checked luggage irrespective of the quantity.
 
Medications and infant and child nourishments are exempted, but the TSA officer must be informed for inspection. 
 
You may carry duty-free liquids over 3.4 oz (100 ml) in your carry-on if purchased internationally, in a tamper-evident bag, with a receipt within 48 hours, and connecting to a U.S. flight.
 

Exceptions on Carry-On Liquids on Southwest Airlines

The TSA provides exemptions to the 3-1-1 liquids rule for some items that could be necessary for passengers to bring on their flight.
 
These exceptions include:
 
  • Prescription Medications: Liquid, gel, or cream medications prescribed for an individual are exempt. They should be clearly labeled to facilitate quick screening.
  • Medically Necessary Fluids: These consist of such things as IVs and other medically necessary fluids.
  • Breast Milk and Baby Formula: These can be transported in more than 3.4 ounces. Ice packs, gel, or freezer packs used to chill them are permissible too.
  • Baby and Toddler Food and Beverages: This consists of puree pouches and other liquid or gel foods for toddlers and babies.
  • Purchases Post-Security: Liquids bought within the airport after clearing security checkpoints can be taken aboard.
 
These exceptions need to be declared by travelers to TSA officers at the security checkpoint and can face extra screening.
 

Southwest Airlines Liquid Rules for Checked Baggage

Southwest Airlines does not have many liquid restrictions in checked bags, providing greater convenience than in carry-ons. Whereas carry-ons have 3.4 oz (100 ml) containers, checked bags have no size limitations on liquids.
 
There are, however, some exceptions:
 
  • Alcoholic Drinks: Alcohol level can be higher than 24% but no more than 70%: It is restricted to 5 liters (1.3 gallons) per passenger and should be in original retail packaging. For alcohol concentration of 24% or less, there are no restrictions in checked luggage.
  • Aerosol Insecticides: Permitted in carry-on luggage under Southwest Airlines liquid policy unless marked as hazardous material (HAZMAT).
  • Duty-Free Liquids: Store duty-free liquids of more than 100 ml in your checked bag even if they are packed in a tamper-evident bag.
 
Seal liquids tightly in your carry-on luggage to prevent any spill or leakage. Double wrap the containers and put them inside sealed plastic bags for additional protection during transport.

What is Southwest Airlines Carry On Weight & Size Limit for Liquids?

For Southwest Airlines Carry-on Bags, liquids have no weight limit but do have size restrictions under the TSA rules.
 
The combined overall size of a carry-on bag cannot be more than 24 inches (L) x 16 inches (W) x 10 inches (H), including handle and wheels. Carry-on bags have no weight restriction, but they must be stowable in the overhead bin or fit under your seat in front of you.
 
For personal carry-on items, it could be a purse, small camera, small backpack, or briefcase. It needs to fit in the seat ahead of you, with no specific size requirements from Southwest Airlines.
 

Conclusion

Southwest Airlines complies with regular TSA rules regarding liquids, with travelers permitted to carry liquids in 100 ml containers or less in their carry-on baggage. Duty-free liquids in excess of 3.4 oz are acceptable if bought internationally, placed in a tamper-evident bag, and supported by a receipt within 48 hours. Passengers are advised to pack liquids in checked bags for excess amounts.
 
Always ensure adherence to TSA rules to avoid any problems during security screening. If you are on a flight schedule that includes Southwest's partner airline, be sure to check their policies too to have a seamless boarding. For any confusion or issues, you may contact Southwest through their website or contact WinkTravelDeals at +1-866-579-8033.
