Apparently, now that the scenario is getting on in years, a number of airllines are experiencing the first round of aircraft D Checks. Bankruptcy has already taken some (me), and looms for others.
I bet on being able to find enough decent aircraft to repalce aging, leased models that were nearing the point of D Checks, but either there were none for lease, the delivery wait for new models was too far out, or there were good used aircraft "for sale" only and out of my price range.
There has got to be a way to get big enough fast enough in a sim to get too big to fail, but after participating in several comeptitive environments, I have not foud it yet!
And, as I hve recently found out, starting afresh at this point and finding useful aircraft in this crowded environment is not easy!
