The ideal carry-on, and a master class in user-centered design

The result of good design is delight, and that's exactly what I experienced when I took my first trip with my new Air Porter backpack. I spent a long time looking for the perfect under seat bag, and this is it. The descriptions on the site don't do justice to how pleasant it is to use this bag. The in-flight pouch at the top of the bag is generously sized for everything I would want to access on an international flight. I became the official document holder for my family, taking over from my much more organized wife simply because the design and placement of the passport/wallet and document pouches are so thoughtful. The water bottle pouch is ingeniously designed to not stick out and add bulk to the bag, and the pouch on the other side is perfect for a laptop charger and other items I'd want readily at hand. The design is so perfect that I rarely found myself needing to access the generous interior pocket. All this and the bag looks classy, stands on its own, and is comfortable to wear. No notes!

Great Expectations

I've been searching for a high quality backpack that fits well underneath an airplane seat and the Air Porter Backpack is exactly what I was looking for. For long flights I like to bring along a small laptop, toiletry bag, tech pouch, light hoodie, noise canceling headphones and the usual accessories that go with these items. All of that fits well with space to spare and are easily accessible.

The backpack looks well made with quality materials. The gold interior fabric makes it easy to look for items in the main cavity. The hide away side pockets do eat into the interior space, but for me that is an acceptable compromise since it prevents my water bottle and other items from falling out and keeps the sides of the backpack neat and clean. As for fit, the backpack feels comfortable and snug. I like that the straps all have clips to prevent any of them from dangling. Being able to tuck the shoulder straps into the luggage pass through slot is also a nice anti-dangling feature.

One thing I would improve would be the rattling from the zippers. It is the only thing that prevented me from giving this backpack five stars. There are eight (8) metal zippers that are all near the top of the backpack and they tend to make a bit of noise while walking. I was able to mitigate much of the noise by using two mini S-biners to secure some of the zippers together. It would be nice to see a more elegant solution for this in a next iteration of this backpack.

Overall, I think this backpack is a great buy and I look forward to using it for travel for several years to come. Well done, Waterfield.

Perfect bag for airplane

Just finished up my first trip to Europe with my bag. The description was spot on, made my air travel much more convenient. The pocket placement is spot on for my organizational needs, the bag has plenty of space, and is comfortable. Will buy again

Mark A. (Massachusetts, United States)
Well built

This backpack is well built as is everything from Waterfield Designs. However, I think it is greatly overpriced. It should sell for half of the $400 price. Just my $.02!

David K. (British Columbia, Canada)
In a word: Perfect

My everyday bag is a Sutter Slim backpack that I use to carry a laptop and iPad, along with all of my cables, chargers, a power bank, a water bottle, and various miscellaneous odds and ends. It's a brilliant backpack but for travel I've always wanted something with just a bit more space.

Enter the Air Porter backpack: When I saw it as a new product, I checked it out and it seemed to be exactly what I was looking for, and so, ordered it. It arrived two days before the website said it would ship, so I commend you on your reverse temporal shipping system, but that's not nearly as impressive as the bag itself.

In anticipation of an upcoming trip I did a test packing of the bag and managed to fit all of my usual tech gear along with three days of clothing and my toiletries. This will be the only bag that have to pack for short trips. On longer trips it will supplement my small carryon bag very nicely, giving me the ability to take just a little more. Should I ever have to (shudder) check a bag, the Air Porter is large enough that I can have a couple of days of essentials with me in the event that my checked bag has an adventure that doesn't include my destination.

The quality of the backpack seems to be up to Waterfield's always high standards and I anticipate that the Air Porter will be my faithful and frequent travelling companion for many years to come. Well done!

Waterfield Air Porter Backpack review: I've never traveled so conveniently with my tech before

Windows Central - September 22, 2023

“...the best tech air travel experience I've ever had. It's not entirely perfect, but it's damn near it.”

Windows Central Verdict: 4.5/5 stars


The Air Porter Backpack meets the maximum allowable personal size item for most airlines. It has two padded compartments for laptops and tablets. These devices can fit in these padded pockets: 

  1. Laptop pocket fits laptops up to 15" x 10":
    • 16" MacBook Pro
    • 14" MacBook Pro
    • 13" MacBook Pro
    • NEW 15" MacBook Air
    • 13" MacBook Air
    • Dell XPS 15
    • Surface Laptop 5 (13.5" & 15")
    • Lenovo X1 Carbon
    • and other similarly-sized laptops 
  2. Tablet pocket fits tablets up to 13" x 9":
    • 12.9" iPad Pro M2 with Magic Keyboard
    • 11" iPad Pro M2 with Magic Keyboard
    • 11" iPad Air with Magic Keyboard
    • Pixel Slate
    • Surface Pro 9
    • and other similarly-sized tablets

NOTE: An optional Air Caddy (for storing an iPad Mini or iPad Air to watch inflight movies) fits in the leather front panel pocket. A larger Air Caddy for 12.9" iPad Pro fits in the main compartment.



The Air Porter Backpack's two top pockets are designed specifically to give you easy access to the items you'll need during your flight. Once you've stowed your backpack under the seat in front of you, you can leave it as is while you zip open the top pockets to get your earbuds, headset, phone charger, etc. 


No need to take your backpack out of its place. Just reach down and grab what you need during the flight. 



To help distribute the weight on your back, we added a triple layer of structural material on the back side and surrounded the Air Porter Backpack with foam padding on the bottom and front. 


This framework also helps the backpack stand upright when you set it down. 



Most backpacks leave straps dangling when you're not wearing it on your back. We've designed a slot where you can tuck the straps in so they stay out of the way. It's a small detail that makes it easier to carry the Air Porter Backapck by the handle, and it gives the backpack a cleaner look.  



We love involving customers in community-design projects because their input often leads to entirely new collections. When we set out to design the Next Generation In-flight Carry and the In-flight Personal Item, we ended up with two types of carry-on bags: the Air Porter (stands up underneath an airline seat) and the Air Duffel (personal item carry-on compliant). 


Customers wanted a third type of carry-on for longer trips: a backpack. The larger Air Travel Backpack complies with carry-on requirements and can be placed in the overhead bin. The new, smaller Air Porter Backpack complies with airline personal item requirements and can be placed under the seat in front of you.  Both carry tech gear and several days of clothing. 


All bags in the Air Travel Collection include special details to make travel comfortable, organized, and more convenient from takeoff to touchdown.  



The bags and accessories in the Air Travel Collection are designed to be carried on board. Some can fit under the seat in front, in the seat back pocket, or in the overhead bin. They meet most airlines' carry-on size requirements so you can avoid checking in luggage.

All have dedicated compartments for holding tech gear so they stay separated from clothes and accessories. The Collection includes the large Air Travel Backpack, the smaller Air Porter Backpack, Air Duffel, Air Porter Brief, and the Air Caddy
