Packing for British Airways Basic in 2026
Your bag must fit within 45x36x20cm when fully packed and closed. Soft-sided bags generally pass sizer tests more reliably than rigid cases - handles, wheels, and zip pulls on hard-shell bags can add 2-3cm and trigger a gate check even when the bag itself is within limits.
British Airways Basic does not publish a weight limit for this ticket type. Check the official policy page before packing to confirm current rules.
Gate fees are always more expensive than pre-purchasing a cabin bag upgrade online. If you are borderline on size or weight, upgrading before check-in closes is significantly cheaper than paying at the gate.
How to make sure your bag passes the British Airways Basic size check
- Measure your bag empty - note length, width, and depth including external pockets and protruding zips.
- Pack fully, then re-measure. Soft-sided bags expand when loaded and can exceed 45x36x20cm even if they measured correctly when empty.
- British Airways Basic does not publish a weight limit. Check the official policy page before flying.
- At the airport, use the bag sizer at the gate before boarding if one is available.
- If in doubt, add a cabin bag upgrade online before check-in closes - gate fees are always higher than pre-purchased upgrades.
