The Tortuga Promise

At Tortuga, our mission is to make travel easier. Our advice and recommendations are based on years of travel experience. We only recommend products that we use on our own travels.

Airlines allow you to bring one carry on and one personal item in the cabin with you when flying.

Most airline publish strict size and weight requirements for your carry on. But not for your personal item.

Airlines’ rules for personal items are not nearly as clear as their rules for carry on luggage. Some airlines don’t publish any rules at all for personal items. The airlines that do have rules don’t have a standard size of personal item that they allow. Even within North America, the sizes can vary by 3-5″ in each dimension depending on which airline you’re flying.

Without clear and consistent explicit rules, travelers abuse the implicit rules.

We’re here to help you maximize your packing while still traveling light and being a good fellow traveler. In this article, we’ll clarify:

  1. What you can bring on a plane as a personal item
  2. How big your personal item can be

We’ll cover what’s generally acceptable since rules vary.

What is a Personal Item?

Let’s start with some definitions.

A personal item is not checked luggage. Checked luggage goes in the cargo hold of the plane.

You’ll bring your personal item onto the plane with you. A personal item is a type of carry on—or cabin—luggage but is not your official “carry on bag.”

A carry on bag is your larger, primary bag, which you’ll stow in the overhead bin. A backpack can be your carry on if it meets your airline’s carry on size limits.

A personal item is a smaller, secondary bag, which you’ll stow under the seat in front of you.

Read Carry Ons vs. Personal Items for more on the differences between the two.

The TSA does not publish a definition for personal items. Personal item requirements are up to the airlines.

While every airline has a different list of acceptable bags, the intention is the same. Here are example personal items from a handful of airlines:

  • Air Asia: “[O]ne (1) piece of laptop bag, handbag, backpack or any other small bag which must not exceed 40cm x 30cm x 10cm. This item must be able to fit under the seat in front of you.”
  • American Airlines: “Your personal item like a purse or small handbag must fit under the seat in front of you. Dimensions should not exceed 18 x 14 x 8 inches (45 x 35 x 20 cm).”
  • Delta: “[O]ne personal item free of charge, such as a purse or laptop bag or item of similar size
  • Lufthansa: “Another small item of baggage (max. x=30 cm y=40 cm z=10 cm, e.g. handbag, laptop bag).”

The guiding principle is that a personal item should be a small bag like a laptop bag, purse, or handbag. A backpack, duffle bag, camera bag, or tote will also work. Do not attempt to put a suitcase, regardless of its size, under the seat in front of you.

For your personal item, think bag, not luggage.

What Else Can You Carry On the Plane?

Most airlines will allow certain small items in addition to your carry on and personal item. For example, you can usually bring:

  • Coat, jacket, or hat
  • Umbrella
  • Pillow or blanket
  • Book or newspaper
  • Food or drinks purchased after clearing security
  • FAA-approved safety seat, stroller, and diaper bag for lap or ticketed child
  • Medical or mobility devices for passengers such as wheelchairs, walkers, canes, crutches, braces, portable oxygen concentrators, and CPAP machines
  • Duty-free merchandise
  • A foot rug for use during prayer
  • Pet carrier

In most cases, the above items do not count as a carry on or as a personal item.

Personal Item Sizes

The sizes of personal items allowed on your flight vary even more than the rules for the type of bag allowed.

The rule of thumb is: your personal item should fit under the seat in front of you.

The personal item allowance is not an excuse to bring a second carry on bag.

I’ve seen people do this and take up two spots in the overhead bin. Don’t be a jerk. Share the overhead bin space with your fellow travelers. The bin is for larger, carry on luggage. You’re allowed to bring a second bag, but that bag must go under the seat in front of you. Don’t steal someone else’s bin space just because you want a second bag without sacrificing your own legroom.

The “under the seat” guideline seems simple enough. But, how much space is under that seat? As a tall person with big feet, the space feels pretty small to me.

Not all airlines provide size guidelines for personal items. The ones that do all have different rules.

Carry on luggage rules can vary but are far more consistent. In the US, most airlines allow carry ons up to 45 linear inches (22 x 14 x 9″). International airlines, especially those in Europe, allow carry ons up to 55 x 35 x 20 cm.

Unfortunately, no such consensus exists for the size of personal items.

Using the same airlines as we did above, we can see that Air Asia and Lufthansa allow personal items up to 40 x 30 x 10 cm. American Airlines, however, allows under seat luggage all the way up to 45 x 35 x 20 cm. That’s a 5-10 cm difference in each dimension. American allows a personal item of double the depth of the other two airlines. You’re allowed a personal item on American Airlines that’s 2.5x the size of your personal item on Air Asia or Lufthansa.

Major airlines in North America, including Aeromexico, Alaska, and Delta don’t publish personal item size requirements. Neither do most airlines in Asia.

The rules, when they even exist, are wildly inconsistent. Our Personal Item Size Cheat Sheet includes measurements for most airlines, but always check your airline’s guidance before flying. 

As with carry on luggage, the more discreet your personal item is, the less likely it is to draw the attention of a gate agent or flight attendant. Keep it small, slim, and inconspicuous. 

Personal Items in Basic Economy

Between 2012 and 2018, most major airlines in America added a basic economy class. Basic economy fares are cheaper than normal economy fares but come with a few added restrictions.

Most importantly, on a basic economy ticket, you are only allowed a personal item, not a carry on. You can only carry one bag, which must fit under the seat in front of you. You cannot put anything in the overhead bin.

If you’re flying basic economy, your personal item goes from being your secondary bag to your only bag.

A basic economy ticket can be a great way to save money, especially on shorter trips where you won’t need as much luggage. A last-minute weekend trip is the perfect time to choose basic economy, save a few bucks, and travel with only a personal item as your luggage.

Does a Backpack Count as a Personal Item?

Yes, a backpack counts as a personal item.

A backpack makes for a great personal item, because it’s small and on your back. When paired with a suitcase or duffel bag as your carry on, a small backpack is discreet and unlikely to be called out by a gate agent. Since size allowances vary so much by airlines, you aren’t likely to find a bag that’s both useful and compliant with every airline. Instead, choose a bag that’s low profile and will fit under the seat in front of you. As long as you aren’t egregiously flouting the rules, you shouldn’t run into any problems.

If you want to carry a backpack as a personal item, use a daypack or a laptop backpack.

Store your personal item under the seat in front of you or on top of your carry on in the overhead bin. Do not use a second spot in the overhead compartment. When I carry two smaller bags, I’ll do this to preserve my legroom without using a second spot in the overhead bin.

As always, your best bet is to pack as light as possible. Don’t give your airline a reason to single you out.

The Best Personal Item Backpacks

When shopping for a personal item backpack, consider two questions:

  1. Is it small enough to fit under the seat in front of you?
  2. Will you be carrying a laptop?

The first question will rule out hiking bags and travel backpacks that can be used for carry ons but are too big to use as personal items.

The second question will help you decide which type of personal item backpack you need.

If your personal item will be your main bag for carrying your laptop—alongside a duffel bag or suitcase as your carry on—choose a laptop backpack that can fit your chargers, cables, and other hardware as well as protect your computer.

If you don’t usually carry a laptop, or will be carrying your laptop in your carry on, a daypack is a better choice. Choose one that’s small and lightweight so that you can wear it around all day at your destination.

Maximize your comfort and organization with the Tortuga Laptop Backpack. You’ll have plenty of pockets for peripherals, plush shoulder straps, and premium weather resistance in a more structured bag.

The short answer is yes, a backpack is a personal item. The caveat is that it must be the right backpack. A small backpack that fits under the seat in front of you.

The airlines’ personal item rules vary so much that it’s impossible to follow them without owning multiple bags or buying one so small that it’s useless to carry.

Instead, follow the spirit of the rules by carrying a small bag as your personal item and avoid drawing attention to your luggage.

5 Expert Tips for Women Traveling With Only a Backpack

Traveling with just a backpack personal item can be a challenge, but our five expert contributors, including founders and a Chief Product Officer, have shared their top tips. From packing essentials for travel complications to enhancing your travel experience with a versatile scarf, these insights will guide you through your next minimalist travel adventure.

Pack Essentials for Travel Complications

When I first started traveling, I always packed an overly-full suitcase. So much so that it became a joke with my fellow travelers! 

These days, I have learned what I truly need, which has paid off with easier commutes and zero baggage fees. If my clients ask what the necessary things they should never leave home without are, I always tell them to pack the items that will help them if they experience travel hassles or complications. 

Of course, there are the standard contents such as identification and a cell phone. But do not forget a fully charged battery power bank, a mini medical kit complete with Band-Aids, alcohol wipes, medications for pain relief or person-specific medical concerns, and items for sun protection like sunglasses, a hat, or a light jacket.

I also recommend other things like a pen with paper, two to three snacks to ensure a clear head if complications arise, and a collapsible water bottle in case you cannot find a consistent source of hydration.

Opt for Versatile and Lightweight Clothing

I’ve found that one tip for traveling with only a backpack as a personal item is to pack versatile and lightweight clothing. Opt for mix-and-match pieces that can create multiple outfits, and choose fabrics that are easy to wash and quick to dry. This way, you can pack less and still have a variety of clothing options. Roll your clothes to save space and use packing cubes to keep things organized.

Furthermore, consider layering your clothing for varying weather conditions. A lightweight, packable jacket or sweater can make a big difference. Don’t forget to maximize your backpack’s compartments and pockets for efficient storage. By following these tips, you can travel with just a backpack as a personal item, stay comfortable, and have everything you need for your journey.

Don’t Forget Your Adapter Plugs

Remember to pack your connectors, especially if you will be a computerized wanderer! Getting one at the airport or upon arrival can be expensive, and they are often surprisingly hard to find. You can purchase a two-pack of EU Connectors on Amazon for only £4.39. Two connectors should be sufficient for your travels to charge and use your computer, phone, camera, hairdryer, and more.

Choose Multipurpose Items for Business Travel

For traveling with just a backpack, especially for business, I think the key is to be ruthlessly selective. Every item in that backpack should serve multiple purposes. For instance, a high-quality, neutral-colored blazer can be a lifesaver. It’s an instant upgrade to almost any outfit, perfect for a surprise business meeting or a casual dinner.

I believe in the power of technology to make life easier, so I never travel without my multi-port USB charger. It’s a small item that makes a big difference, allowing me to charge multiple devices at once, be it my smartphone, tablet, or laptop. This is particularly crucial for business travel, where being connected is not just a luxury but a necessity.

For female travelers, I’d recommend packing a lightweight scarf. It’s incredibly versatile, serving as a fashion accessory, a blanket, or even a makeshift bag in a pinch. Plus, it takes up almost no space!

Enhance Travel with a Versatile Scarf

As a digital nomad and constant traveler, hopping from one place to the next, I’ve learned a lot about packing smart and living out of a backpack. It’s been crucial in helping me get around smoothly and even in cutting down on travel expenses.

When traveling with just a backpack as a personal item, consider packing a versatile, lightweight scarf or sarong. Not only does it add a fashionable touch to your outfits, but it can also serve multiple purposes. You can use it as a shawl for chilly evenings, a beach cover-up, a picnic blanket, or even a makeshift curtain for added privacy in shared accommodations. Plus, it’s a handy accessory that takes up minimal space in your backpack but can greatly enhance your travel experience.
