What are the Southwest liquid rules for checked baggage?

Southwest Airlines has few restrictions on liquids in checked baggage, offering more flexibility compared to carry-on luggage. While carry-ons are limited to 3.4 oz (100ml) containers, checked bags can hold liquids of any size.

However, there's one important exception:

Alcohol: When packing alcohol in your checked bag, the total quantity cannot exceed 5 liters (1.3 gallons) per passenger, and the alcohol content must be under 70% by volume.

To avoid leaks or spills, it's wise to pack liquids securely in your checked baggage. Consider double-wrapping containers and placing them in sealed plastic bags for extra protection during travel.

Additional Considerations:

• Medications and Baby Formula: These are allowed in quantities exceeding 3.4 ounces but must be declared for inspection at the security checkpoint.
• Duty-Free Items: If you're traveling internationally, ensure that duty-free liquids stay sealed in their tamper-evident bags with the receipt visible for security checks.

By following these guidelines, you can make your travel experience with Southwest smoother and avoid any unexpected issues at the airport.
