The person who took the photo says its a A321. Although, I am not sure if it is the same a/c. I tried googling WWBO, and saw that a bunch of A3xx with a temporary registration of F-WWBO.
So I guess my question is, Could it be, that this a/c is new enough, that they took the F off and put a G, while waiting for the permanent registration? If so, how do I actually find out what this a/c is?
I think that myaviation.net photo was taken before the aircraft went on lease. As the photo is a bit blurry, the photographer misread the rego. If you look closely, you can see that the registration is probably G-WWBD (and the aircraft is obviously an A330, not an A321).
