We go again next September and when I came back this year, thought I had better check out the seats on the plane. I checked last night and there wasn't that many rows of 4 left so I would advise everyone to check when they can. You can find out your VA reference number by putting in your VH reference number first and details of the flight number etc on the VA site. When it recognises you, then your VA reference is given in the top left of the screen so just copy it down for next time - its definitely easier when you can use the proper reference number!
