An airport ecosystem is quite complex. Airports don't actually hire ground crew. That is done by the airlines, but there are a number of vendors throughout the airport, a number of companies and people from Nav Canada and government agencies, and a RAIC, which is your authority to get through to the secure area, is certainly a hot commodity these days. A challenge across our airport ecosystem is that people within that ecosystem who have RAICs are sometimes moving from company to company within the airport.
