Part of the accounts feature Passenger Numbers and Aircraft Movements, so in general for cross referencing purposes, thus if CAA results are two months behind then obviously that has an impact.
Freeports are a good thing. They are not a hindrance to companies or transporters it doesn't slow down any custom processes. It helps saves companies located in freeports lots of money on import duties when they import stuff to work on/ process then export it back out of the country. Hence why Willis liked the airport freeport location. They can bring aircraft in do work on them and send them back out without any import duties. Those getting broken the import duty isn't classed as an aircraft, but as scrap metal and rubbish, thus lowering duty levels, so it is good business sense for Willis.
