What’s the Best Carry-On Size for British Airways? (And Why 56x45x25cm Works)

Flymax Luggage

If you’re planning a trip with British Airways (BA), it’s crucial to know the exact size your cabin bag must be. Getting it wrong could mean extra charges, last-minute check-ins, or even a frantic airport repack. But don’t worry—we’ve got the details right here.

📅 Step 1: Understand BA's Hand Luggage Policy

British Airways allows two items in the cabin:

  • One main cabin bag: Max dimensions 56 x 45 x 25 cm (including wheels/handles)
  • One personal item: Max dimensions 40 x 30 x 15 cm (fits under seat)

Keep in mind that your combined weight must be under 23kg. If traveling on a Basic fare, you may need to upgrade to include a cabin bag. This is where the 56x45x25cm size shines—it’s perfectly designed for British Airways' guidelines while maximizing space.

🔗 Bonus: It saves you time by skipping check-in lines, and no lost luggage!

🛂 Step 2: Why 56x45x25cm Is the Ideal Choice

The 56x45x25cm size offers incredible benefits:

  • Maximum cabin allowance: This size ensures you can utilize British Airways’ full dimensions without extra charges.
  • Spacious yet portable: Big enough for 4-6 days of travel but compact for overhead storage.
  • Universally versatile: Though tailored for BA, this size works well for most international airlines that allow larger carry-ons.

🌏 Step 3: Choose a Bag That Maximizes the Allowance

We recommend the Flymax São Paulo Glide 56x45x25cm. It ticks all the boxes:

  • Soft-shell for flexible packing
  • Durable, water-resistant material
  • Lightweight design to keep you under 10kg

Also available in our Cabin Luggage Collection, including multiple sizes that meet airline-specific dimensions.

🚀 Final Tips Before You Fly

  • Always confirm your fare tier—Basic fares may restrict you to a small personal item unless upgraded.
  • Weigh your packed bag at home to avoid surprises at the airport.
  • Label your luggage clearly with your name and contact details for added security.
