Stop Airlines changing Carry-On Luggage sizes -Create a standard UK Minimum Size

The lack of a standard carry-on size across airlines doesn’t just cause confusion — it creates waste. Travelers are forced to buy different bags to meet constantly changing airline rules, leading to unnecessary spending and the production of bags that may only be used once. This cycle of overconsumption contributes to environmental harm. A UK-wide minimum cabin bag size of 45 x 36 x 20 cm would reduce waste, promote sustainability, and create a fairer, simpler travel experience for everyone.
