One can only assume you are kidding, or have not seen the list of even European only airlines that have gone out of business. Aircraft are not going to be a problem.
Wet leasing may be, but the travel market is still depressed by mass unemployment across the European zone, so I don't think that will be so much of a problem either.
And then we get on to the "non-striking strikers", volunteers and new hires.
I don't see any problem; this strike will probably be less effective than the last, and may weed out much more of the useless BASSA flotsam and jetsam.
