The European Parliament adopted new EU rules today that aim to make air travel safer from attack.
The rules harmonise in-flight security and cover areas such as the use of sky marshals and carriage of weapons on aircraft for the first time on a pan-EU level.
They also harmonise screening of passengers and cabin luggage, access control and security checks. The rules have already been approved by the 27 EU member states.
But the European Parliament and EU states could not agree on who should pay for what in aviation security, and the bloc's executive European Commission will make separate proposals on this later in the year.
Each EU state determines how much of the cost it, the airports, carriers or users should bear for aviation security, but further measures are envisaged to ensure that security charges are used only to meet security costs.
EU states are free to introduce stricter rules but must show that doing so is "relevant, objective, non-discriminatory and proportional" to the risk, according to the regulation.
The rules also provide a common EU approach to dealing with unruly passengers and access to the cockpit. They also allow individual EU states to introduce air marshals if they want to. However those air marshals must be specially selected and trained.
Also under the new rules, passengers and their baggage on flights from third countries will not need to be re-screened if their country of origin has aviation security standards deemed equivalent to the European Union's.
