As others have said, they check less often than previously. However they do still check bag sizes. Maybe one or two people per flight, instead of three quarters of the flight.

Simple solution is just to make sure your case is less than 55x40x20cm and don't overfill it. I have this case: http://www.argos.co.uk/static/Produc...er/9100073.htm It fits nicely into the sizing cage and seems to maximise the amount of space. I can easily fit five changes of day clothes, towel, a travel kettle and a pair of shoes into this case.

I know Bologna Airport previously experimented with an automated weighing and measuring machine (encased in a structure similar to an x-ray device) prior to entering security. If you baggage failed, you were denied entry to the security area and were directed to the ticket desk. Not sure if this is still the case or whether this machine has spread elsewhere.
