This post was a very good one. I like when you have someone that will give you a list of the same type of product in different price ranges. This one was a very good post as he had everything laid out in an easy to follow outline. My question is why is there a question if it would fit into an overhead bin? There should be a set standard and all should have to meet those. If that is the case, and the bag meets those standards, the bag should fit if it doesn’t why would you buy the bag?
I hope this helps support your question regarding standard size. Airline and aircraft specifications dictate the size of overhead storage bins, with variations abound. The standard dimensions for carry-on bags are typically 22 x 14 x 9 inches (56 x 36 x 23 cm), taking into account handles and wheels. Certain domestic carriers, like Southwest Airlines, may allow baggage slightly exceeding these dimensions, such as 24 x 16 x 10 inches. It’s worth noting that bin capacity also hinges on the type of aircraft utilized, with newer models often boasting more spacious confines.
