I guess there is a silver lining to all this, and that is delaying the penalties that they will have to pay to remove the leased A320s from the fleet. Most leases still have a few years to run.
Other option is to bin the 737 fiasco and keep the Airbus. I really fail to see the point in all this mess for a token fleet of A320s, even more so that they are no longer going to Bali.
With rumoured potential new leadership changes at Virgin upcoming don't think it can be ruled out.
