I think there's a dichotomy. Many of what we call the legacy carriers continue to do their maintenance in-house. Carriers that have been newly created in the past 30 years almost never do their maintenance in-house. They seek a more efficient, specialized solution.
Even among the legacy carriers we're seeing a strong movement to contracting out, especially the heavy maintenance, Qantas, for example. Australia is a bit smaller country than Canada, but geographically it's similar. We're colder, and Australia is tipped on its side. Most of the activity is on the east coast. Qantas now does almost all its heavy maintenance through outsourcing, some of it in Australia and some of it elsewhere.
