The 3:1:1 rule on Spirit Airlines refers to the TSA liquid rule for carry-on bags. Since Spirit Airlines operates under standard U.S. TSA security regulations, this rule applies to all Spirit Airlines passengers, including those who booked flights directly through Spirit or through third-party platforms like expedia travel and expedia travel flights. Many travelers only discover this rule at the airport security checkpoint, leading to frustration, item confiscation, or delays. This comprehensive, 1,000+ word guide will help you fully understand what the 3:1:1 rule means, how it applies to Spirit Airlines, how to pack your liquids correctly, what Spirit Airlines allows in personal items, and why calling +1-808-900-6212 can help you prepare for your trip.
Whether you're traveling for business, vacation, school breaks, or family trips, you need to know the full TSA guidelines that apply to Spirit Airlines. Since Spirit Airlines follows a low-cost, minimalist baggage structure, passengers often carry only a personal item to avoid bag fees. Because of this, understanding the 3:1:1 liquid rule is even more important when traveling on Spirit Airlines, especially when you are packing smart to avoid extra charges. If you're unsure how the 3:1:1 rule applies to your specific journey—especially when booking through expedia travel or expedia travel flights—you can call +1-808-900-6212 for personalized packing and baggage guidance.
What Exactly Is the 3:1:1 Rule?
The 3:1:1 rule is a TSA (Transportation Security Administration) guideline that applies to all U.S. airports and therefore applies to every Spirit Airlines passenger. The rule is simple:
✔ 3 ounces (3.4 ounces/100 ml) or less per liquid container
Your liquids must be in containers no larger than 3.4 ounces (100 ml).
This includes:
Shampoo
Conditioner
Lotion
Liquid makeup
Face wash
Gel
Perfume
Hair products
Toothpaste
Sunscreen
Mouthwash
Passengers who frequently book using expedia travel or expedia travel flights often rush through checkout and forget to check TSA requirements. To avoid issues later, always verify your container sizes or call +1-808-900-6212 for help.
✔ 1 quart-sized transparent bag
All your liquid containers must fit into one quart-sized clear plastic zip-top bag.
Approved bags include:
Quart-size Ziploc bag
TSA-approved transparent travel pouch
Bags not allowed include:
Gallon bags
Large makeup pouches
Opaque travel bags
Cloth bags
✔ 1 quart bag per passenger
One passenger = one liquids bag.
This applies whether you fly alone or in a group—even if booked through bundled packages like expedia travel flights.
If you need guidance preparing your quart bag, you can call +1-808-900-6212 for TSA-approved packing advice.
Does Spirit Airlines Enforce the 3:1:1 Rule Strictly?
Yes.
Spirit Airlines follows TSA security rules with zero exceptions, because TSA controls the screening process, not the airline. Whether you booked through Spirit Airlines directly or through expedia travel or expedia travel flights, the security requirements remain identical.
If you try to carry more than the allowed liquid sizes, TSA will confiscate the items, and delays may occur. Spirit Airlines cannot override TSA rules in any airport.
Passengers who fly light to avoid Spirit baggage fees often pack all toiletries in their personal item, making the 3:1:1 rule especially important for Spirit flyers. To avoid mistakes, contact +1-808-900-6212 before packing.
Why the 3:1:1 Rule Matters More for Spirit Airlines Travelers
Spirit Airlines operates with an ultra-low-cost model, which means bags cost extra unless you’re bringing only a personal item. Because of this:
✔ Many Spirit passengers travel with minimal luggage
✔ Most Spirit travelers avoid large liquids due to fees
✔ Toiletries must fit into the 3:1:1 TSA-approved format
✔ It is essential to pack carry-on liquids correctly to avoid confiscation
Expedia users booking Spirit Airlines flights through expedia travel or expedia travel flights often forget that a Spirit personal item (like a backpack) is small and requires efficient packing, making the 3:1:1 rule even more essential.
If you're unsure whether your personal item is big enough to handle your quart bag, call +1-808-900-6212 for assistance.
What Liquids Are NOT Allowed in Carry-Ons Under the 3:1:1 Rule?
Regardless of whether you booked through Spirit or expedia travel, the following items cannot pass through security in full-size containers:
Large shampoo bottles
Full-size aerosols
Large mouthwash
Full-size lotion
Big sunscreen bottles
Large perfumes
Full-size hair products
Bottles over 3.4 oz/100 ml
If you want to bring these, you must:
Put them in a checked bag
Or leave them behind
If you need help determining whether a liquid is allowed, call +1-808-900-6212.
What Is Considered a “Liquid” Under the 3:1:1 Rule?
TSA considers anything that can spill, smear, spray, or pour as a liquid, including:
Makeup foundations
Mascara
Lip gloss
Gel deodorants
Hair gels and wax
Oils
Creams
Toners
Liquid food (soup, yogurt, sauces)
These rules apply to all Spirit Airlines passengers, including those who booked using expedia travel.
Exceptions to the 3:1:1 Rule
Some items are exempt from the 3:1:1 restriction:
✔ Medications
Prescription and certain over-the-counter medications can exceed 3.4 oz but must be declared.
✔ Baby Formula & Breast Milk
These are exempt and must be screened separately.
✔ Special Medical Liquids
Medical solutions or equipment fluids may exceed 3.4 oz with approval.
