SimonC ,
PE is definitley worth it at this price. We flew PE in March and it makes your journeyl so much easier. I am now really looking forward to the flight. Its not just bigger seats it all the little perks that go with it that make it a great package.
ie dedicated check in, first on plane after Upper, more personal attention from cabin crew, first off plane, first to customs baggage, car hire etc.
The only problem with PE is going back to economy !
Our excuse for upgrading is not only the good deal on the price, but also because my wife willl be 20 weeks pregnant when we fly.
BTW The 10% frequent Virgin discount applies to the PE seating upgrade aswell. So it will work out at £450.00.
