I used this bag for 2+ weeks in Europe. We went to several cities in Germany, Brussels and London. My mom and I both had one as our carry on. We packed light. I had 2 pairs of shoes, 3 pairs of pants and a dress I think. I am plus size with large feet.

All black will draw less attention at the check in counter. see less Yes...we flew LAX to Paris CDG on Norwegian 777 with two Porter 46 packs.

As far as I know, the dimensions are a little different. Same 46 liters and maybe more pockets. I went with the newer model for the color to my husbands dismay, since it's $50 more.

The new 2017 has a lockable, U-shaped zip for the main compartment just like the old model. Main differences are: Lockable laptop compartment at the back of the pack (including an additional zippered pocket inside the laptop compartment large enough for an iPad, which is also a good place for documents e.g. passport), … see more The new 2017 has a lockable, U-shaped zip for the main compartment just like the old model.
