Yowza, that’s a lengthy period to keep $ making iron on the ground due to maintenance (not scheduled heavy MX checks), routing issues and especially when betting on higher earning rates and having a decreased usage rate. Aside from obvious profit margins aircraft (heavy aircraft) need to fly consistently at frequent intervals keeping internals and flex to prevent significant maintenance impact. Two weeks isn’t a deal breaker, but definitely not advantageous for airframes aside from the normal wear and tear of substantial sorties. As a former maintainer, keeping aircraft aloft became exponentially harder and harder the longer they sat and after a month or so we were very wary it may become a hangar queen. Granted, sometimes it was necessary to have one down for parts for an elongated period to keep the rest going.
