International Carry-on vs. US Carry-On

International carry-on size restrictions can be notoriously challenging since so much of the restrictions are determined by where you are traveling. Here's a breakdown on just what to look for with your next trip.

Outside of the U.S. the standard carry-on baggage size is smaller (this relates to flights originating outside the U.S. and with a destination outside the U.S.) Here, the rule of thumb is about 21", and not the 22" and above carry-on size. As with any rule, exceptions abound and it is a good idea to visit the site of all of the carriers you plan to use while abroad to get a consensus. If you travel outside the U.S. on a regular basis or are looking to purchase a bag for someone who does, you might want to consider replacing the standard domestic sized carry-on bag in your set with an international carry-on sized bag. In terms of what the two bags will actually hold the difference is not that great and it may add some flexibility in your travels.

I love this bag!


I am a small woman and was looking for a light weight bag that would fit under the aisle seat on Southwest Airlines (my airline of choice). I have the larger Osprey rolling carry on and love it. So I decided to try this bag. It's great!! I like the different compartments, it's light enough to carry easily when full and if I put the handle first, it fits under the seat! Love it!



Fits more than you would think


International trip wanted to avoid carryon size problem. Also wanted to avoid using a backpack for my carryon - no longer want to carry weight around. Loved the various pockets. I was able to put all I needed into the bag. My only problem was the single rod handle - I was unable to bungee a tote bag to the Osprey. It would drop around to the other side immediately. Would like to see Osprey develop a bungee for a single rod handle.



Fantastic bag, rugged, spacious and light!


I bought this bag for a trip to Europe to replace my old 22" e-bag roller that was getting flagged as too big for the cabin on one of their airlines. Safe to say 4 trip within Europe and the airlines don't even blink at it. My most recent trip was 6 weeks of trains and planes and the odd auto, This bag was FANTASTIC! I used it to mostly clothing (6 days clothing in packing cubes) and items I was likely not to need during travel. It's size and weight made it easy to haul on and off trains, up stairs and fit into overhead bins. It was also able to carry the little EagleCreek bag I used as my day pack in it. This bag plus a 22 liter backpack (for camera, tickets, etc,} were all I required for six weeks travel. I stuffed it to the gills and the seams and zippers had no trouble with what I threw at it. The only thing that bothered me, very occasionally, was the single stemmed handle - I could not put my backpack over it to carry through airports with long walks to the gate - anything placed there would inevitably slide around. Wish they could fix that. Love this little bag and it will have a long future!



The Greatest


I have owned the Ozone 18-in for 5 years and it has been my constant companion on trips with just this carry-on and another Osprey backpack. I have traveled with it for 20 days and it can fit enough wash and wear clothing. From cruises, to Hong Kong, to Japan, to Mexico, mainland USA, beach resorts in Asia and it has held up very well on trains and buses as we like to do DIY trips. I like the pockets it has and the wheels are durable on rough terrain. My husband has an older version of the same size and a tad heavier but works just the same. We own several sizes of Osprey backpacks (just to have) depending on what activity we are doing.

Honolulu, HI


Perfect carry on


The 18" carry-on served me well for two weeks in the UK (my hiking boots took up almost 1/3, but there was still room for everything else I needed,) two weeks in Morocco, a week-long visit to Hawaii, a five-day trip to San Francisco.... Light, manageable, and reasonably easy to organize content. I'll probably opt for the next size up for longer trip to Europe. Just curious about how well it might hold up when chucked around by baggage handlers on check - in flights.

Vancouver Island

versatile light bag that holds way more than you think!


We used two of these bags for a family trip to Europe. The compression straps held everything snug and gave loads of room. They were super lightweight and our kids ages 7 and 9 handled them with ease. The side handles were great for carrying up and down stairs at underground stations. We used transit everywhere and budget airlines and these were the best bags ever! No problem with overhead bins even on the stingiest airline allowances. We now want one for each family member!

Only if it was also a backpack


Would be a great bag if there was a way to attach some backpack straps. Other than that which I personally consider a serious design flaw. The bag is very well though out well tons of cool pockets.
