According to thousands of Amazon shoppers, the Kroser 16-inch Underseat Carry-on Luggage is perfectly suited for such a task. This on-sale rolling underseat luggage can fit several days' worth of clothing and is flush with functional details, earning a stamp of approval from travelers and even flight attendants; one shared that they use it as a "turn" bag, which is a piece of luggage that flight crew members use for turnaround flight assignments that require a brief layover.
There's an art to packing a carry-on bag: everything has to be accessible, organized, and serve a purpose. As a carry-on-only traveler, I'm big on packing my personal bag with intention and keeping my luggage as streamlined as possible; as such, there are a few tried-and-true products I always pack. Luckily, Amazon's stacked travel deals section always gives me a great excuse to stock up on those travel essentials that make all the difference.
