totally incorrect. The FAAA has an iron clad guarantee that you have the right of return to mainline at the expiry of the two years. Some time before the two years are up you will be asked whether you wish to return or extend..(still retaining the right of return) . if you decide to return to mainline you will give the approximate date you wish to return and CC Management have "GUARANTEED" your return give or take a bid period to ensure not everyone returns at the same time.
If that occurs it will be staged over two bid periods to ensure proper balances and transfers back to A380 from mainline.
QED thats it!
