TSA Carry-On Rules & How to Pack Like a Pro

Nothing derails a trip faster than getting flagged at the security checkpoint. Whether it's an oversized bag, a forgotten liquid, or a lock that TSA has to cut off, these are all avoidable problems. Here's what you need to know before you get to the airport.

TSA Carry-On Size Limits

The TSA doesn't set a universal carry-on size — airlines do. Most major carriers allow a carry-on up to 22" x 14" x 9" (including wheels and handles). Our Legacy 21" Carry-On Spinner ($229.99) is sized to fit in the overhead bin on virtually every major domestic carrier. USA assembled, 8-spinner wheels, expandable main compartment, and a free custom monogram. It's the carry-on we'd put on anyone.

The Liquids Rule (3-1-1)

You already know this one, but it's still the #1 reason bags get pulled at the checkpoint: all liquids must be in containers of 3.4oz or less, all fitting in one quart-sized clear bag, one bag per passenger. Keep it at the top of your carry-on so it's easy to pull out at the bin.

Use a TSA-Approved Lock

Regular locks get cut off. TSA-approved locks have a universal keyway that agents can open without destroying your lock. Our Lieber's Lab TSA-Approved Cable Lock ($11.99) is a no-brainer addition to any checked or carry-on bag. The Briggs & Riley TSA Cable Lock ($20) is a step up if you want something more heavy-duty.

Pack Smarter With Cubes

Packing cubes aren't just for organization — they make security screening faster because your bag is easier to repack after it's been searched. Our Legacy Packing Cube Set ($49.99) is built to match the Legacy carry-on perfectly. The Eagle Creek Pack-It Reveal Cube Set ($64) is another favorite for frequent flyers who want a see-through option.

What Can't Go in a Carry-On?

The TSA's prohibited items list is long, but the most common surprises: snow globes, gel shoe inserts over 3.4oz, lithium batteries over 100Wh, and any sharp tools. When in doubt, check TSA's What Can I Bring tool before you pack.
