Plan a flight with cabin bags only

Read the allowance for each booked flight

Check your reservation and the operating airline’s current baggage page. Distinguish a small under-seat item from a larger bag for the overhead locker. Confirm whether your fare includes both or whether another booking option is needed. Repeat this for the return flight and any connection operated by a different carrier.

As a concrete example, easyJet currently describes its included small cabin bag as a maximum of 45 × 36 × 20 cm, with handles and wheels included. That is an easyJet rule, not a universal cabin size. Measure the fully packed bag, including bulging pockets, and use the allowance applicable to your own booking. easyJet cabin bags.

Pack the trip rather than a collection of possibilities

Lay out clothing by actual days and activities. Choose items that work together and remove duplicates that solve the same problem. Put the outfit for a fixed event aside before trimming general clothing, and check whether your accommodation offers a realistic laundry option. Avoid relying on a wash that cannot dry before the next move.

Choose the footwear you will wear while travelling and justify any second pair by a specific activity. Use small containers only where the product and applicable security rules allow them. A soft backpack may fit your needs, while wheels may be more manageable for another traveller; assess carrying comfort and usable space instead of treating either style as automatically better.

Check every security checkpoint on the itinerary

Airport security restrictions and airline baggage allowances answer different questions. GOV.UK says liquid rules have changed at some UK airports and directs passengers to check the airport before travelling. Check your outbound, transfer and return airports individually. An item accepted at the first airport may still need to meet different screening arrangements later. GOV.UK hand luggage overview.

Keep items that may need separate screening accessible. Make a list of toiletries before packing them so you can remove unnecessary duplicates. Do not assume that partially empty large bottles satisfy a container-size limit. If you need to carry an item covered by an exemption, read the relevant airport guidance and its document requirements before leaving home.

Prepare for a bag being placed in the hold

Have a compact pouch ready for travel documents, keys and essentials you must retain. Check the carrier’s instructions for batteries and electronic devices. British Airways explicitly tells passengers to remove spare batteries and power banks if cabin baggage is taken at the gate and placed in the hold. Follow the rules of your own operating airline. British Airways restricted items.

Do not buy a power bank solely on a claim that it is travel-friendly. Check its marked specification against the airline’s current limits and usage instructions, and pack it as directed. Keep enough space to move necessary items into your permitted smaller bag or pouch without spilling the entire contents of your luggage at the gate.

Rehearse once with the bag fully loaded

Close the bag, measure it and weigh it if your allowance has a weight limit. Carry or roll it over the kind of route you will face, then practise reaching your passport and liquids without repacking. A bag that only closes with unusual force is unlikely to be comfortable to manage repeatedly during a trip.

Before the return flight, repeat the measurement and contents check. Separate anything newly purchased that affects security or baggage restrictions and decide how it will travel. Keep the airline allowance saved with your booking so you can resolve packing questions from the actual terms. If the trip needs more capacity, compare adding the appropriate baggage before departure with changing the packing plan.
