I've not flown yet, we are going on 1st June, but a friend of mine has just returned and has said the aircraft was great.
New Virigin Livery, Nintendo Games, All the entertainment, seat back TV's and flight attendants who wanted to give a good service.
The only problem he encountered was with the child meals as they ran out beforer reaching his children, even though he had pre ordered. The flight going was 20 minutes early landing and the flight coming back was even better.
He did fly on the 1st May though which was the first flight out.
I don't know if anyone else has had any different experiences.
Hope that helps, it certainly helped me.
