Can this bag be carried on a plane?

I have been using the 60L as my go to carry-on for about 3 years now. On larger airliners it fits with no problem but on smaller planes they tend to make you check it at the door. What's great about checking it at the door is that you don't get hit with the checked baggage fee. I have never had anyone stop me and tell me that the bag is too big to be considered a carry-on. This thing is burly as hell and seriously roomy, the only problem is that it gets heavy, and when you travel as often as I do, you start dreaming of wheels. So unfortunately I am soon going to retire this beast for air trips in favor of one of the snazzy Dakine rolling pieces. Still love this bag. Even have the size small, which I believe is a 30L, that they don't sell anymore which I have used as my gym bag for years.

It depends what you mean by "carried on". This would have to go in the hold, not as carry-on luggage. Beware in the US - The luggage restrictions are not just weight, they are ased on overall dimensions. No single piece of luggage is permitted to exceed a total dimension of 62" (ie W+H+L). Looking at the specs, the 9154cu in is 16+38+21=75", and the 6100cu in is 14+19+32.5=65.5". So you could get slugged with oversize luggage costs. Also beware cos these duffels are seriously big, and weight becomes a problem if you don't pack with discipline!
