One cubic foot. That’s roughly how much volume airlines grant you for the 9 inch x 10 inch x 17 inch “personal item” that goes under your seat. It’s a tiny allowance. Sure, you have a bit more space in your bag stored in the overhead bin. But nowadays many airlines are charging you for overhead bin access (THANKS, basic economy). Even if they don’t, nobody wants to be that guy who gets up every hour to get things from the overhead bin — especially if you’re sitting in the window seat.

So if you fly frequently, you put a lot of thought into what goes into your under-the-seat-in-front-of-you storage. The contents of your inflight go-bag are probably a good window into your personality and priorities when it comes to flying. In the spirit of sharing, I’ve compiled a list of the five essential things that I always have in my carry-on bag. Some cover the basics necessities, some are for fun, and some are for the AvGeek in me. And once you’re done reading my list, let’s hear what’s on yours!

So little space. So much potential!

Heads up: this is not a sponsored article and I have no business relationship with any of the items I mention. Though if anyone at any point does have a desire to give me money for any reason whatsoever, please don’t hesitate to get in touch.

1. Foldable water bottle

Planes are dry places. It’s not because the folks at Boeing, Airbus, et al have a master plan to turn the human race into raisins. It’s because humidity causes corrosion. And nobody likes a rusty plane.

Unlike your average aircraft, the human body does not like to get dried out. So staying well hydrated is critical. But your inflight H2Options can be limited. If you come aboard with nothing you’re at the mercy of your flight attendants, who may or may not make their water rounds often enough for you.

So boarding with your own water is the way to go. Standard solid plastic bottles work fine for most people. But if you’re really space conscious, then consider a collapsible bottle.

I purchased a Vapur flexible and collapsible water bottle (maybe “pouch” is the better word) before a marathon four-flight itinerary from North America to Europe to Southeast Asia. And on that trip — and every flight I’ve taken since — it’s served me well. When I don’t need it, it rolls up to the size of my fist. But after I clear security and hit my first water fountain, it expands to hold a full liter. It’s never unexpectedly sprung open or leaked on me after hundreds of refillings — which is important if you have your electronics in your bag as well. Here’s an Amazon link.

Water anyone?

Anyone remember the old-school self-serve water dispensers on United’s 747s?

2. Black hooded sweatshirt

When you’re working with limited storage space, versatility is key. And when it comes to versatility, I found that the simple hoodie is the unsung hero of my travel wardrobe. Here’s three great reasons why:

  • When you’re flying, layering is your best friend. You may go from a 90-degree summer day outside the airport, to an overly chilled terminal. Then you board a plane that’s turned into a toaster after sitting in the sun for a few hours, only to become an icebox after you hit cruise and the air conditioning ramps up.
  • Climate at your origin â‰  climate at your destination. You may not have had the foresight to pack an umbrella, but at least with a hoodie you’re covered in a pinch.
  • For me personally, the three biggest threats to getting sleep on a flight are: (1) light, (2) noise, and (3) feeling exposed. My trusty hoodie tackles all three. When I’m trying to sleep, I take my hoodie and put it over my front side, with the hood covering the front of my head. The hood blocks out light and even muffles some ambient sound, while the rest of it acts like a blanket. The reverse-hoodie look probably freaks out my neighbors a bit. But it’s worth it for a good night’s sleep.

3. Two-pronged headphone adapter

If you fly enough and can afford them, noise-canceling headphones are a flyer’s best friend. Unless they meet their nemesis: two-pronged headphone jacks. That’s why it’s worth investing in a simple, cheap adapter, which will ensure you can make use of those amazing headphones you brought.


4. Monocular

There are wonderful views to be had from the windows of a jet. And the views are even better if you can zoom in on specifics, like cities or other aircraft sharing the skies. Most people would think of binoculars, but I find a monocular to provide good views in a much smaller package. After all, space in your go-bag comes at a high premium.

5. Suction cup smartphone mount

What if you’re not satisfied with just taking in the views. What if you want to capture them? For your friends? For Facebook? For the Insta?

My personal favorite form of aerial photo/videography is the time-lapse video. But holding a camera or phone still against the window for ten full minutes isn’t easy. So I picked up a suction-cup iPhone mount — the type that you might have in your car. I attach it to the window, twist the arm so the phone camera is pointed out of the window, and voila! Steady videos captured with ease.

Here’s the setup:

And here’s the result:

Honorable mention: a burrito

Compact. Tightly wrapped.Not strongly odorous. Filling. Perfectly edible at room temperature. Yes, all are descriptors of the humble burrito, which makes for the ideal carry-on meal. I get mine with sour cream and guac, which usually registers as a gel in the TSA scanner. Still, the inconvenience is worth the deliciousness.

If you’re flying Lufthansa first class, you can probably skip the burrito

So what’s on your must-pack list?

Now for the best part of this article: where you all get to chime in. What do you always have within arm’s reach when you’re on a flight? Who knows — maybe you’ll start a trend! We look forward to seeing your must-pack list in the comments section below.

Good choice on the bag! I’ve got a couple of the Pan Am bags (one like yours, the other a larger one, with zippered pockets on both ends.) VERY handy to stash wallet, ID holder, spare change, etc when going through the security scanner. Plus I ALWAYS get comments about the bag (old enough to have flown Pan Am – and my wife actually worked on the business deal in the mid 1980s to keep Pan Am from going bankrupt – which it eventually did, folding for good in 1992.)

Doug Bowen

collapsible water bottle, Chapstick, small fleece blanket, trail mix bags-usually 2-3, chewing gum, small bottle with lotion, Tylenol & Rolaids, small toiletries bag – foldable toothbrush, mouth wash, antimicrobial soap, Clorox wipes and extra set of batteries and two prong plug.

Isn’t a 2 prong headphone adapter pretty useless unless you also have a pair of headphones?

Bill Helbig

Having been a commercial pilot for 26 years, I have had a lot of time to perfect my travel routine – what to bring, what not to bring. While most people might have a handle on that, many people don”t think about a method for keeping track of the things they”ve brought and inevitably leave something behind. Rule number ONE. Never place any item in the seat back pocket in front of your seat. The old adage ”out of sight, out of mind”, certainly applies when one is exposed to the many stresses of flying these days. Rule number TWO. This especially applies to families with kids. Take off of the airplane the same number of items you brought on – 3 children on should be the same for getting off the airplane. Count the number of carry on bags and other items such as jackets, hats, and electronic equipment. That way, one does not have to remember what exactly a person boarded with 5 hours earlier in the day, but rather only having to recall a certain number. Much easier to remember and way less stressful on an already stressful day!!

Small hand sanitizer and/or wipes, gum, snack, water bottle (I buy one in the airport before boarding), phone wall charger, earbuds, book, tablet with a couple movies downloaded on it. All my flights are 3 hrs or less so I rarely sleep.

Headphones, breath mints, tablet, chargers for stuff (phone and tablet). International flights: add basketball shorts and a t-shirt if I am not in F.

ear plugs. a small pack of tissues – these are useful in multiple situations.

Alex Tambiev

Wallet, portable charger, usb phone cable (both for use with the charger and if there is a USB port in the seat), pack of mints or gum, and actually that”s about it. This article has made me realize that I don”t really carry anything special for flying…

Victor Jones

1. Bottle for water
2. Wet tissues
3. Noise canceling headphones
4. Low carb snacks (nuts)
5. Tabasco / chili powder to make in-flight meals palatable
6. Disinfectant

Alex Tambiev

This actually made me remember something I forgot to mention in my comment: noise canceling headphones, obviously. And a lightning port adapter in case I feel like listening to music on my phone.

I never travel without a pen. Black ballpoint.

you are right if you”re flying international you need a black ballpoint pen.

Great article! And great replies. I usually have a combination of what’s already been listed: Clorox wipes, noise canceling headphones, phone charger/cord, tablet for longer flights, Tums, ibuprofen, light jacket, mints, small bag of snacks, toothbrush/toothpaste. Usually all contained in a small backpack or small tactical shoulder pack.

Chris Miller

An eye mask, hooded rain jacket, and noise cancelling headphones with lightening plug splitter with charger will allow me to fly around the world sleeping, looking out the window, and listening to endless hours of aviation podcasts. The best part I have nothing at my feet for maximum space for me.

Top five basics: Water bottle, hooded light jacket, gum, snacks, tablet+headphones.

Honorable mentions go to: Toothbrush, magazines, earplugs.

All great ideas, I need specially lot of water to prevent a bad headake. Airplane water is not the best quality, so i buy some and for more I refeel a plastic cont. Other things needd – skin moisturizer (for guy as well) and lipstick, good book or a magazine if you van concentrate and can it easy

Jasper Frame

Never drink the dispenser water.

Great lists! Keep ’em coming

Margaret Greene

Kindle, shawl ( serves the same purpose as the hoodie), Neck pillow, small toiletries bag, headphones after a few years of not watching the films as I should not make out what they were saying! I also have to take some food as I have Celiac disease and never know when the airline will forget my special meal


Kindle, small knitting project (socks or mittens), noise canceling headphones, water bottle and a long, rectangular shape pashmina scarf.

1. A ziploc bag with assorted snacks.
2. Windbreaker/collapsible umbrella
3. A paperback book or two.
4. Boarding passes.
5. Wallet/passport…all the important ID.
6. Phone/iPad/chargers.

Ok that’s more than 5, but I can’t think of anything I would take off the list.
