Carry-on Policies Compared
Carry-on baggage rules vary widely among airlines. Understanding these differences helps travelers avoid extra costs and stress. Southwest Airlines has its own clear policies for carry-on bags. Comparing these rules with other airlines shows the benefits and limits of each.
Southwest Vs Other Airlines
Southwest allows one carry-on bag plus one personal item per passenger. The carry-on must fit in the overhead bin. The personal item should fit under the seat.
Many airlines also permit one carry-on and one personal item. However, size limits and definitions of personal items differ. Some airlines have stricter size rules or allow only a personal item without a carry-on.
- Southwest: 1 carry-on + 1 personal item
- Delta: 1 carry-on + 1 personal item
- American Airlines: 1 carry-on + 1 personal item
- Spirit Airlines: 1 personal item only (carry-ons require a fee)

Fees And Charges
Southwest does not charge for the first carry-on or personal item. This policy contrasts with some budget airlines.
Spirit and other ultra-low-cost airlines often charge fees for carry-on bags. These fees can be high and vary by route and booking time.
| Airline | Carry-on Fee | Personal Item Fee |
|---|---|---|
| Southwest | $0 | $0 |
| Spirit | $35-$65 | $0 |
| United | $30-$60 | $0 |
| Delta | $0 | $0 |

Tips For Packing Carry-on Bags
Packing your carry-on bag smartly can make your Southwest flight much more comfortable and hassle-free. You want to fit everything you need without exceeding the airline’s size and quantity limits. The trick lies in organizing efficiently and choosing essentials wisely.
Maximizing Space
Use packing cubes or compression bags to squeeze more into your carry-on without creating a mess. Rolling clothes instead of folding them saves space and reduces wrinkles. Place heavier items at the bottom and fill gaps with smaller things like socks or chargers.
Have you ever struggled to close your carry-on last minute? A personal trick is to wear your bulkiest shoes or jacket on the plane to free up room inside the bag. Also, keep liquids in clear, resealable bags for easy access during security checks.
Essential Items To Pack
Focus on what you truly need during the flight and at your destination. Always pack your travel documents, a phone charger, and a small toiletry kit. A lightweight jacket or scarf can be a lifesaver if the cabin gets cold.
Think about comfort and convenience: noise-canceling headphones, a neck pillow, and snacks can improve your travel experience. Don’t forget a reusable water bottle—Southwest allows empty bottles through security, so you can fill up after the checkpoint.

Special Considerations
Southwest Airlines has clear rules about carry-on bags, but some travelers face unique situations. These special considerations can affect how many bags you bring or what you can carry onboard. Understanding these nuances helps you avoid surprises at the gate and makes your journey smoother.
Families And Children
Traveling with kids often means juggling more than just your own bags. Southwest allows one carry-on bag and one personal item per passenger, but what if you have a stroller or diaper bag?
Good news: you can bring a stroller or car seat in addition to your carry-on allowance. This means you don’t have to sacrifice your extra essentials for your child. However, if you bring multiple kids, each child still gets the same baggage allowance.
Think about packing smartly—can you consolidate smaller items into one bag? It’s easier to manage your belongings and keep your hands free for little ones.
Traveling With Sports Equipment
Sports gear often challenges standard carry-on rules due to size and shape. Southwest lets you bring one carry-on bag and one personal item, but sports equipment typically counts as a checked bag.
Some equipment, like golf clubs or skis, require special handling and fees. However, smaller items like tennis rackets or yoga mats might fit within your carry-on allowance if they meet size restrictions.
Ask yourself: can your gear fit safely in your carry-on without risking damage? If not, check it in to avoid stress at boarding and protect your investment.
Updates For 2026
Southwest Airlines has introduced some important updates for 2026 regarding carry-on bags. These changes affect how many bags you can bring and what rules apply. Understanding these updates helps travelers avoid extra fees and delays.
Policy Changes
Southwest now allows one standard carry-on bag per passenger, unchanged from previous years. The size limit remains at 10 x 16 x 24 inches. Passengers may also bring one personal item, like a purse or laptop bag.
