Always arrive at the airport early when traveling with a pet. Check-in will take a few minutes longer, and some airlines ask for a visual inspection of your pet and carrier. Plan, and you and your four-legged companion will be ready for takeoff!

Carry-On and Personal Item Size Restrictions

Your carry-on bag should fit in the overhead bin and should not be larger than 24 x 16 x 10 inches, including handles and wheels. Your item-such as a backpack, purse, or laptop bag-should be small enough to store under the seat in front of you. Going over these sizes could cause your bag to be checked at the gate.

Things You Can Pack in Your Carry-On Without Restrictions

Southwest lets you bring essentials like electronics (phones, tablets, laptops), chargers, books, snacks, and even refilled water bottles. Toiletries are permitted under the 3-1-1 TSA rule: gels and liquids in 3.4 oz (100 ml) containers stored in one clear quart-size plastic bag. Medications, infant formula, and breast milk also qualify-even bigger quantities-when declared correctly.

What You Shouldn't Bring in Your Carry-On

For the safety of passengers, pointed objects, firearms, inflammables, and sports equipment such as bats or hockey sticks cannot go in your carry-on. They should either be placed in checked luggage or remain at home. Also, don't carry power banks above 100Wh because they are banned and can be taken away.

To breeze through airport security, pack your liquids and electronics in accessible spots. Label your bags, keep travel documents handy, and double-check TSA and Southwest guidelines before packing. Being organized saves time and ensures a smooth start to your journey.

Pro Tip: Save Time at Security
