Carry-on luggage: the complete 2026 guide

Carry-on suitcase, cabin luggage: understanding the useful difference

On a plane, a carry-on suitcase is stored in the overhead bins. Cabin luggage also includes your personal item (backpack, handbag) placed under the seat. Both formats complement each other: the carry-on suitcase for clothes and bulky items; the under-seat item for keeping documents, medication, headphones, and chargers within reach.

Choosing your cabin luggage correctly avoids last-minute fees, speeds up security checks, and ensures you keep your essentials close by. Airlines apply specific standards: external dimensions (handles and wheels included) and total allowed weight. Below is a clear table to help you pack your carry-on suitcase and your under-seat item for major airlines, from Air France cabin luggage to Ryanair cabin luggage and the weight allowance at easyJet.

Official dimensions: airlines (cabin & under-seat)

Dimensions are given in height × width × depth (cm). “Cabin” = overhead bin; “Under-seat” = personal item. Always check your fare (Basic, Priority, Plus…), which may determine your right to a carry-on suitcase.

Traveling by train: TGV INOUI vs OUIGO (formats and flexibility)

On high-speed trains (TGV), flexibility depends on the service. TGV INOUI allows two large bags + one small bag per traveler, without systematic weighing. OUIGO applies a strict format framework: one small bag and one carry-on suitcase, with an option for an additional or XL bag.

Essential criteria for a good carry-on suitcase

• Dimensions compliant with the airlines you fly with most often.
• Low empty weight to maximize what you pack.
• 360° double wheels for effortless maneuvering.
• TSA lock and reliable zipper for peace of mind.
• Organized interior: dividers, pockets, securing straps.
• Clear warranty and replaceable parts (handles, wheels).

Hard-shell or soft-side: which type suits your usage?

A hard-shell carry-on suitcase better protects its contents thanks to its shell (polycarbonate, ABS, sometimes aluminum), resists impact, and maintains its shape. A soft-side cabin bag is lighter, more flexible, often features very practical exterior pockets, and is sometimes expandable. Your choice depends on your trips: frequent city breaks with strict airline constraints? Opt for a reliable hard shell. Varied travel, train + plane + car with a need for quick access to pockets? Prefer a quality soft structure.

Hard-shell luggage comparison: GYL vs Delsey

GYL Signature (cabin): polypropylene shell, 360° double wheels, TSA lock, and lifetime warranty. Inside, there are true integrated storage solutions: compartments, zippered pouches, and dividers. Result: a stable, secure, and organized suitcase that ages well.

Delsey (e.g., Châtelet Air 2.0 cabin): Parisian image, elegant finishes, modern rigid materials, TSA lock, and careful interior organization. Delsey excels in style and reputation; however, the warranty is generally time-limited, and the interior architecture sometimes proves less modular.

To remember: if you prioritize durability + repairability + organization, GYL takes the lead; if you prioritize brand signature + heritage look, Delsey remains a safe bet. In any case, aim for a 55 cm format to secure boarding.

Soft-side luggage comparison: GYL vs Lipault

GYL Évasion (cabin): waterproof and tear-resistant polyurethane material, chic textile style, multiple exterior pockets, double wheels, and very smooth gliding. The interior is compartmentalized and the entire bag remains lightweight, with the GYL lifetime warranty reinforcing the long-term investment.

Lipault (e.g., Original Plume cabin): ultra-light nylon, minimalist silhouette, and trendy colors. Lipault shines in lightness and urban allure, but protection and long-term repairability are more limited than on a premium-positioned GYL carry-on suitcase.

To remember: for ultra-light, stylish, and occasional use, Lipault is appealing. For an elegant, resistant, and repairable soft-side bag, GYL scores points, especially if you travel often and want to keep a reliable cabin suitcase for years.

Organization and usage tips

The key to an effective cabin bag: isolate essentials in the under-seat item and reserve the carry-on suitcase for bulky pieces. Remember to group cables and small tech in a pouch, roll your clothes to limit wrinkles, and place liquids in a transparent, accessible pocket. A luggage scale avoids bad surprises at the boarding gate; on the train, favor storage in dedicated areas rather than the aisles.

Care and durability of carry-on suitcases

• Hard-shell: soft cloth + neutral soap; avoid solvents.
• Soft-side: soft brush + waterproofing spray if necessary.
• Dry completely before storage to prevent damp odors.
• Store upright, away from direct sunlight and heavy objects.
• Prioritize brands offering replaceable wheels/handles.
