The EU has been urged to increase its extension on carrying liquids in hand luggage at European airports.
Current rules, which were introduced in 2006 and are due to expire in April 2010, are now likely to be kept in place until 2014.
According to the rule, passengers are allowed to carry liquids in containers with a maximum capacity of 100ml.
The EU says it intends to bring in a phase-out plan when the current ban is lifted, and all member states will have the upgraded new 'type C' scanners installed by 2012 and begin the screening process by 2013.
The scanners need to be tested and certified by member states for use upon completion of the upgrade.
The new 'type C' scanners can detect more than 20 types of explosive liquids.
The EU's transport committee has inked an alternative proposal and is expecting the commission's approval.
