Travelers flying with British Airways often ask one important question before heading to the airport: Can I bring both a backpack and a carry-on bag? The short answer is yes. Under the current British Airways carry on size policy, most passengers are allowed to bring 1 cabin bag and 1 personal item onboard. This means you can usually carry a backpack along with your main carry-on suitcase without extra charges if both items meet the airline’s size and weight rules.
Understanding the rules before your flight can help you avoid delays, extra fees, and unexpected baggage problems at the gate.
British Airways Carry On Size Rules
The official British Airways carry on size allowance includes:
1. Main Cabin Bag
- Maximum size: 56 x 45 x 25 cm
- Maximum weight: 23 kg (51 lbs)
2. Personal Item or Backpack
- Maximum size: 40 x 30 x 15 cm
- Examples include:
- Backpack
- Laptop bag
- Handbag

Your backpack must fit under the seat in front of you, while the larger carry-on goes in the overhead compartment.
BA Baggage Allowance Explained

Even if your fare does not include checked luggage, you can still bring both a backpack and carry-on onboard if they meet cabin baggage rules.
British Airways Bag Weight Limit
One major advantage of flying with British Airways is the generous British Airways bag weight limit for cabin luggage. Each cabin bag can weigh up to 23 kg, which is more flexible than many airlines.
However, passengers must still be able to lift their bags into the overhead bin without assistance.
British Airways Overweight Baggage Fee
If your luggage exceeds the allowed size or weight limits, you may need to pay a British Airways overweight baggage fee. Charges depend on:
- Route
- Fare type
- Weight exceeded
- Airport vs online payment
Overweight baggage fees are usually more expensive at the airport, so weighing your bags before travel is recommended.
Tips to Avoid Extra Baggage Charges
1. Measure Your Backpack Before Flying
A large hiking backpack may exceed personal item limits.
2. Use Lightweight Carry-On Luggage
This helps stay within the British Airways carry on size and weight rules.
3. Keep Essentials in Your Backpack
Store passports, electronics, medications, and travel documents in your personal item for easy access.
Final Thoughts
Yes, you can bring both a backpack and a carry-on on British Airways as long as they follow the airline’s cabin baggage policy. Knowing the British Airways carry on size, BA baggage allowance, and British Airways bag weight limit before departure can save you from last-minute stress and costly baggage fees at the airport.
