This personal item bag guide covers everything a budget-conscious traveller needs to know, from why the under-seat slot has become the most valuable piece of real estate in aviation to which bags fill it best. Baggage fees are no longer a minor inconvenience: according to LuggageWiz, Frontier alone collected $861.6 million in baggage fees in 2024, a figure that underlines just how aggressively no-frills carriers have monetised the overhead bin. JetBlue moved further in the same direction in 2025, introducing dynamic pricing for checked bags, meaning the cost of simply packing a suitcase can now shift depending on when and how you book.
Why the Personal Item Has Become Essential
On carriers such as Frontier, or when booking a basic economy fare on a full-service airline, the personal item is the only bag you can bring aboard without paying a surcharge. Get the choice right and you sidestep the fee entirely. Get it wrong, either by picking a bag that is too large or by misjudging the airline’s specific dimensions, and you are handed a charge at the gate.
Sizing varies more than most travellers realise. Frontier permits a bag up to 8 inches deep, 18 inches wide and 14 inches tall. United’s allowance is 9 by 10 by 17 inches, Delta’s is 9 by 13 by 17, and Southwest stretches to 8.5 by 13.5 by 18.5 inches. Allegiant is the most restrictive at 7 by 15 by 16 inches. Checking your specific airline before buying is not optional; it is the first step in any personal item bag guide worth following.
The Best Personal Item Bags, Tested by Editors
The editors behind this selection test hundreds of products each year. Their criteria focus on three areas: storage capacity relative to the bag’s footprint, design versatility, and the quality of extra compartments for toiletries, chargers and similar travel essentials. Price range runs from $14 to $595, covering options for the committed budget flyer through to the traveller looking for an investment piece.
At the entry level, the Narwey Foldable Travel Duffel Bag ($14) is made from waterproof polyester, folds flat for storage, and comes in 34 colourways. One reviewer reported fitting four days of clothing and two pairs of shoes with room to spare. For slightly more, the Lubardy Travel Backpack ($38, originally $40) adds three packing cubes, a wet pocket for laundry or toiletries, and reinforced zippers. A reviewer confirmed it cleared American Airlines’ personal item requirements with a week’s worth of clothing packed inside.
The Amazon Basics Underseat Carry-On ($49) stands apart from most bags on this list because it has wheels, constructed from ballistic nylon with internal sections including a dedicated shoe compartment. Dimensions sit at 13.4 by 14.2 by 9.5 inches. The trade-off is that it runs smaller than photographs suggest.
In the mid-range, BÉIS Travel accounts for several of the editors’ picks. The Mini Weekender ($108) (the smaller sibling of the brand’s bestselling Weekender) opens with a wide clamshell zip that lets you see everything inside at once, and carries a padded laptop sleeve plus a bottom compartment for shoes and hair tools. Former assistant shopping editor Anvita Reddy described it as fitting the right amount for a three-day trip, with room for a few extra outfits when packed efficiently. The Commuter Duffle ($119, originally $158) holds 24.2 litres, stands on five metal feet, and comes in water-resistant nylon with vegan leather handles. Former assistant shopping editor Kyley Warren took it as her sole bag on a recent trip, packing seven outfits, two pairs of shoes, a toiletry bag and a portable steamer.
For those who need structure rather than softness, Calpak offers two hard-shell options. The Hue Mini Carry-On ($185) has a polycarbonate shell, a TSA-accepted lock, and four 360-degree spinner wheels. The Ambeur Mini Carry-On ($215) shares the same wheel and handle setup and opens upright with a divider and multiple internal pockets. Reddy noted it functions as a miniaturised full carry-on, describing it as capable of holding enough for a three or four-day weekend despite its compact dimensions.
At the higher end, Away‘s Overnight Bag ($228) is built from water-repellent nylon with a leather trim, holds approximately 28 litres, and includes a 15-inch laptop pocket with a trolley sleeve and a detachable shoulder strap. The Cotopaxi Allpa 35 L Travel Pack ($230) is cut from 100 per cent recycled fabric, opens on three sides to lay flat, and is the pick for trips where hiking or camping is involved alongside any flying. For those who need every item categorised and accessible, the Nomad Lane V4 Bento Bag ($298) includes a tech pouch, toiletry pouch, shoe bag, two internal compartments and two security-friendly top-access pockets. Contributing shopping editor Angela Elias packed a computer, tablet, chargers, headphones, two changes of clothes, pyjamas, toiletries and an extra pair of shoes inside it.
The Shinola Canvas Duffle ($595) closes the list as the investment option: heavyweight cotton construction with leather-accented dual straps, a generous centre pocket and two snap pockets on either side. Dimensions are 14 by 20 by 7.5 inches. It is available in one colourway and is aimed squarely at the traveller who wants a bag to last for years rather than seasons.
With JetBlue’s dynamic bag pricing now in effect and other carriers watching closely, the financial case for mastering the personal item allowance has rarely been stronger. The next update to this selection is set to add the Quince Water Repellent Puff Expandable Tote and the Calpak Weekender Duffel.
