The Osprey Porter 46 and the Aer Flight Pack 2 are two top dogs in the world of carry on backpacks. Both are worth considering, but differences in size, compatibility and material might sway your preference one way or another. Let's dig into the specifics.

The `Osprey Porter 46` is a big, robust backpack that seems to never run out of space with a height of 23 inches, width of 36 inches, depth of 56 inches, and weight of 1.5 pounds it boasts 46 liters of capacity. Although it’s tough as nails, built from durable Nylon, it’s compatibility with airlines is limited to 47%. On the plus side, it can a fit a 1 inch laptop handily. Reviewers rave about its durability, vast organization options, and rugged appeal. It’s something that holds its own value for any journey, and comes with a very competitive price tag of only $140.

The `Aer Flight Pack 2`, on the other hand, is sleek, light, and compact. It measures 46 inches tall, 31 inches wide, and 13 inches deep, lightly tipping the scale at 1.3 pounds. What this pack lacks in sheer capacity (providing 21 liters), it makes up in adaptability -- accepted by a whopping 98% of airlines. Constructed out of 1680D Cordura ballistic nylon, it’s also tough and durable. Impressive is its ability to hold a 16 inch laptop along with being adaptable, it can switch roles as a briefcase, backpack, or messenger bag. Critics commend its variety of organization options, adaptability and modern look.
