Hand Luggage Only: The Complete Guide to Flying Light

🎯 Key Takeaways

Hand luggage only (HLO) is the single most effective way to reduce both the cost and the friction of flying. No hold bag fees, no 20-minute wait at baggage reclaim, no risk of lost luggage, and faster check-in. With the right packing strategy, you can travel for two weeks with nothing more than a 20-litre daypack.

Understanding the allowances

Every airline has slightly different rules:

• Free underseat bag (all budget airlines): roughly 40 x 20 x 25 cm. This is the free allowance at the base fare.
• Overhead cabin bag (requires Priority or extra fee on Ryanair/Wizz; included on easyJet/BA/KLM standard): typically 56 x 45 x 25 cm, up to 10 kg.

For most trips, an underseat bag is sufficient if you pack efficiently. For longer trips or if you need a laptop and change of clothes, upgrade to a cabin bag — but factor in the fee at the time of booking, not at the gate.

The core packing system

Choose the right bag

A 20-litre backpack or a cabin bag within airline dimensions is the foundation. Look for bags with a clamshell opening (easier to pack and unpack) and a laptop sleeve if you travel with a computer.

Recommended capacity:

• Weekend trip: 20–25 litres
• One week: 30–35 litres
• Two weeks: 40 litres (requires a disciplined packing list)

Use a capsule wardrobe approach

The biggest mistake is packing outfit-by-outfit. Instead, pack interchangeable items:

• 3 tops (neutral colours that all work with your bottoms)
• 2 bottoms (trousers or jeans that are presentable for evenings)
• 1 jacket or mid-layer (doubles as warmth on the plane)
• 3–4 days of underwear (wash at the hotel every two to three days — takes minutes, dries overnight)
• 1 pair of shoes worn on the plane

This covers 7–10 days comfortably.

Toiletry rules (EU carry-on)

Liquids in the cabin must be in containers of 100 ml or less, all fitting in a single 1-litre clear resealable bag. To avoid having to think about this:

• Buy a set of small refillable bottles (50 ml) for shampoo, conditioner, and shower gel
• Use solid toiletries where possible (solid shampoo bars, solid deodorant)
• Buy toothpaste at the destination for stays over four days

What to wear on the plane

Wear your heaviest and bulkiest items on the plane: boots, jeans, thicker jacket. These take up the most space in a bag and weigh the most. Wearing them eliminates the problem.

Electronics

Charge everything the night before departure. Take only what you will actually use:

• Phone (always)
• Laptop or iPad (only if genuinely needed)
• Charging cable and a single compact GaN charger with multiple ports
• Earphones

Avoid taking both a laptop and an iPad — pick one.

Financial benefit

On Ryanair, adding a Priority boarding pass (for the overhead cabin bag) costs around £6–8 per flight segment when booked in advance. On a return trip that is £12–16. On Wizz Air, the small cabin bag upgrade is similar. On easyJet, a standard hold bag costs £10–25 per segment.

Travelling hand luggage only saves £20–50 on a typical budget return flight. On three or four trips per year, that is £60–200 in bag fees alone — before the time saved at baggage reclaim.
