Waiting for comments from Spanners please !
Frankly January 2015 seems far to early for the resumption and where are the available frames ?
I do know they have outstanding 77Ws but don't know their delivery scheduled.
One would also presume use of the three class models and right now they numbers a sum total of just 9 aircraft. 4 of which currently fly the off peak Heathrow service 1 each to Vancouver and Toronto plus 2 to New York.
So almost certainly looks to need a upgrade elsewhere to accommodate Manchester.
Certainly possible.
I want to believe this is true and i've written elsewhere the justifications for the viability along with others after a US correspondent questioned Manchester .
