TCX's airline business is now in material decline.
If the deal with EZY works well, why wouldn't they seek growth from type of operation that rather than the massive hastle of running an airline operation (on top of everything else within TCX).
The Sale & Leaseback of the Boeings suggests however that the airline business will remain for the medium term, but TCX came close to failure and therefore change is required by the city. It would be very easy for management to say that the move away from hard assets (shops/airline etc.) is the sure way to gold.
If nothing else, it buys them a few years.
