744 or 343

Of the last six VS011 LHR - BOS flights, 5 have been shown as a 744. The Virgin Atlantic site for this flight on 23 May shows the aircraft to be a 343. What are the chances of:

a. the flight actually being a 744 and

b. being able to choose upstairs PE seats for our flight[?]

I do appreciate that there is still a fair way to go until the trip but I'm sure some of the experts here will have some input:D

This is one of those flight's that keeps changing from 744 to 343 to 346,there are a couple of flights that switch from 343 to 346 it seems like every day LHR - IAD.

I understand where your coming from,it's a pain with the way VS's fleet has so many,shall we say standards.
