The Bellroy Classic Backpack Plus (hereafter referred to simply as "Bellroy") and the Aer Fit Pack 3 (let's call it "Aer") are two leading picks among frequent flyers. Each shines in their own way, so let’s put these contenders side by side for comparison sake.

The Bellroy offers a little more packing room with its 22 litre capacity compared to the Aer's 18.7 litres. This backpack is also slightly larger with dimensions of 21x30x52 inches. The Aer, however, surprisingly weighs less. When made to measure against the altitude rulers of major airlines, the Aer has a better compatibility rate, fitting the size requirements of 83% of airlines versus Bellroy's 65%. Both bags can handle a laptop, but the Aer has an edge here too – it accommodates a laptop of up to 16 inches versus Bellroy's 15.

Judging by reviews, users appreciate the attention to detail in both backpacks. Each has been lauded for their admirable craftsmanship and practical design. Both make good companions for the daily commuter, but the Aer seems to outshine the Bellroy in handling the work-gym transition.

Here's a quick rundown of the differences.

In conclusion, Bellroy sets the bar high with its sleek design and organizational potential that has the reviewers nodding in approval. On the other hand, the Aer, while slightly smaller, presents itself as a highly versatile pack delivering on many fronts - from daily commute to gym sessions. It's also slightly more airline-friendly and makes room for a larger laptop. In the battle between the Bellroy Classic Backpack Plus and the Aer Fit Pack 3, it all comes down to user requirements and personal style. Both of these backpacks have standout features to suit different needs.
