No idea but the accreditation must be lax when Luton got it if and when the following areas were examined. This award is more about the processes put in place rather than the practicalities of using it.
All passenger areas and processes are considered including terminal access, check-in areas, security screening, boarding gates, lounges, retail, food and beverages, gate equipment such as boarding bridges, escalators and elevators, border control areas and facilities (in collaboration with authorities), baggage claim area and arrivals exit.
Screens have been put up for the check-in desks to protect staff but when vast areas of check-in desks can be unused why is there side by side check-in of passengers?
The airport would have paid for this just like they paid £2000 per car park for Park Mark accreditation for its car parks. They were claiming Park Mark for their priority parking when open waste ground was being used for the storage of passengers cars before the gateway bridge was built opposite the Ibis. Maybe it was just an oversight but it did undermine the integrity of the scheme when half the site was not even fenced.
