Thanks Cindy
I called Just You for a rough price. It's more than I expected but not out of my price range. Still not decided what to do although the nice lady at Just You said she would call me back in a few weeks with more details of the price and stuff.
I've just come back from Turkey on a delayed night flight and couldn't get to sleep at all. At least if I upgrade you can get the seat at a better angle to sleep and the extra room would be good.
There's a long time to go yet so no rush to book the upgrade yet. Would still like to hear from anyone who has had an upgrade though.
Thanks
Paul
