Southwest Airlines Carryon Bag Policy

You know that pre-flight panic when you’re trying to stuff a sweater into an already-overflowing duffel bag? We’ve all been there. But when you fly Southwest, you can take a deep breath, because their carry-on policy is basically the unicorn of air travel: generous, simple, and—dare I say—fun.

Here’s the skinny: every passenger gets one carry-on bag and one personal item (like a purse or laptop bag) for free. Yes, free. No hidden fees, no side-eye from the gate agent. The bag just needs to fit in the overhead bin, so keep it under 10 x 16 x 24 inches. That’s roughly the size of a very ambitious weekend getaway. Pro tip: That “personal item” can be a surprisingly bulky tote—I’ve seen people sneak in a small ukulele and a bag of snacks from the airport Cinnabon. (No judgment, that’s efficiency.)

Now, the secret weapon of Southwest? There are no weight limits for carry-ons. So go ahead, pack that brick of novels for your beach trip. You’re only limited by physics—and your own strength when you hoist it up. (Your biceps will thank you later.)

One playful warning: Southwest boards in groups (A, B, C), and the earlier you check in, the better your bin space. Show up late with a giant roller bag? You might get the dreaded gate-check—which is like sending your bag to summer camp without you. It’ll be fine, but you’ll miss it.

So next time you fly, remember: Southwest’s policy is basically a high-five from the airline gods. Pack your favorite oversized hoodie, your secret stash of gummy worms, and that novel you keep saying you’ll finish. You’ve got this. And when you breeze past the baggage claim with your rolling suitcase and a smug smile, give yourself a little pat on the back. You’re a carry-on champion. Now go enjoy your trip—may your overhead bin always be empty and your gummy worms never melt.
