Packing your underseat carry-on bag Dimensions

Underseat luggage dimensions vary by airline, but a general guideline is 18 x 14 x 8 inches (45 x 35 x 20 cm). It’s crucial to ensure your bag fits entirely under the seat without obstructing legroom or the aisle. Always check your airline’s specific requirements for the most accurate information.

Tip: Opt for bags around 16 x 12 x 6 inches (40 x 30 x 15 cm) to leave some wiggle room.

Key Features to Look for in an Underseat Carry-On Bag

Bag Material and Mobility

When considering the features of underseat carry-on bags, it’s important to weigh the advantages and drawbacks of different bag materials and mobility options to find the best fit for your travel needs. 

Hardside vs. Softside

For underseat storage, softside bags are typically more practical due to their flexibility. However, hardside bags provide better protection for delicate items and enforce a disciplined packing approach.

Feature	Hard side	Soft side
Material	Rigid (plastic, polycarbonate)	Flexible (fabrics)
Benefits	Solid protection, fixed structure	Expandable, adjustable, better fit under seats
Ideal for	Delicate items, disciplined packing	Flexible packing, maximizing capacity

Wheeled vs. Non-wheeled

Wheeled bags allow you to quickly move through terminals without lugging weight on your shoulders. However, they may take up legroom once stowed underseat.

If you don’t mind carrying your bag, a non-wheeled underseat bag optimizes in-flight space. But it’s a trade-off for airport convenience.

Feature	Wheeled	Non-wheeled
Benefits	Easy transport	More in-flight legroom
Drawbacks	Takes up more leg room	Needs to be carried

Packing Your Underseat Bag Like a Pro!

So now that you’ve got the perfect underseat bag for your trip. Now it’s time to master packing it! Follow these tips and tricks to get the most out of your limited space:

1. Use Packing Cubes/Organizers

Packing cubes and organizers are essential tools for maximizing space and organization in your underseat bag. These versatile accessories neatly separate or compress different categories of items, allowing you to optimize every inch of available space.

Opt for slim, lightweight designs available in various sizes to accommodate different types of items. Clear plastic cubes provide easy identification of contents, while different colors or sizes further enhance organization.

2. Choose Multi-functional Clothing

Since space is limited, pick versatile clothing that mixes and matches. Stick to 2-3 neutral-colored tops and bottoms in lightweight fabrics. Choosing a minimalist, multi-functional wardrobe lets you do more with less in your underseat!

Other tips:

• Roll clothes tightly rather than folding
• Use packing cubes to compress
• Wear the bulkiest clothes and shoes
• Layer shirts/sweaters for warmth over T-shirts

3. Portable Comfort Items

Don’t sacrifice comfort just because you’re traveling light. Be sure to pack:

• Blanket – Choose a thin, lightweight travel blanket rather than a heavy one. Can be used as a pillow or for warmth.
• Earplugs/noise canceling headphones – Block out crying babies and engine noise to rest.
• Sleep mask – Nap whether it’s bright daylight or dark nighttime.
• Small pillow – Inflatable or stuffed pillow to provide neck support.
• Non-slip socks – Stay cozy and avoid feet swelling on long hauls.

These items take up minimal room but make a big difference in your in-flight comfort!

4. Smart Electronics and Accessories

You’ll want your electronics and chargers close, but avoid bulky laptops and accessories. Prioritize:

• Phone – Your in-flight lifeline. Have headphones accessible.
• Tablet – More comfortable for watching movies vs. phone.
• e-Reader – Travel light with digital books rather than print.
• Portable charger – Recharge devices without fighting for outlets.
• Adapters – Bring a multi-port USB cube and international plug adapters.
• Noise-cancelling earbuds – Better than bulky headphones.

5. Only Essential Toiletries

You’ll want access to a few key toiletries on a flight.

• Small toothbrush and trial-size toothpaste – Brush away food and coffee breath
• Cleansing wipes – Freshen face and hands without lugging liquids
• Lip balm – Avoid chapped lips in dry cabin air
• Hand sanitizer – Kill germs from fellow “germ tubes”
• Tissues/medication – Have relief close for runny noses or headaches
• Hairbrush/ties – Look refreshed after a nap with quick grooming

Tip: Transfer essential liquids to travel-size containers to save space.

6. Pack What Brings You Joy!

Along with the useful things, don’t forget to bring some treats for the ride, such as:

• Snacks – Nuts, protein bars, or favorite treats
• Entertainment – Downloaded movies, books, games
• Comfort item – A small pillow or blanket from home
