A340 at Manchester yesterday

I was near the airport yesterday, saw a VS A340 land around 12.45pm, it wasn't showing on the arrivals at MAN, just curious as to why it was there?

I saw an A346 come into LGW on Saturday morning and go straight to a gate. My assumption was it was a hurricane disruption buster. Perhaps you saw the same one and it was rotated in the States

Exactly that.
G-VWIN operated the 15 and then back as the 74 into MAN.

And now she's in Manila for maintenance ...
