The European Union is set to introduce a new batch of rules aimed at making flying simpler and less unpredictable.

Changes to hand luggage regulations are set to come into force on September 1 as part of a plan to standardise the dimensions of carry-on bags.

At the same time, the rules for carrying liquids on planes will revert to a universal standard.

Until now, airline companies have been free to set their own terms regarding hand luggage measurements.

This has led to a confusing number of rules about the allowed weight and the size of carry-ons, which have often caught out even the most experienced travellers.

The new EU regulations will impose uniformity across all European airlines, meaning passengers can now expect standardised baggage sizes and weights.

Below is a summary of the EU rules governing hand luggage that will apply to all travellers from the start of next month.

Weight allowed: No more than 10kg.

Cabin allowance: 1 cabin bag and 1 small personal item such as a handbag, backpack, or laptop bag that must fit under the seat in front of you.

Maximum dimensions: Maximum dimensions (including handles and wheels), are set to be 55 x 40 x 20cm, and the personal item should be 40 x 30 x 15cm.

The EU has also decided to reimpose previous rules concerning the amount of liquid passengers can take on flights.

Currently, travellers passing through terminals equipped with Explosive Detection Systems for Cabin Baggage (EDSCB) have been able to carry liquids in quantities greater than 100ml.

It has now been decided to scrap this exception until all airports in Europe have the same screening device.

From September 1st onward, the familiar 100ml rule will be reinstated for all passengers.

The EU has said that this uniformity is necessary for now, but further adjustments could be made in the future as airport security technologies continue to evolve.

The new changes should hopefully make life a lot simpler and less frustrating for travellers.
