For such a long flight I would say that POUG it's worth it. See this thread for what POUG means and I'd also recommend taking a look at the BA Forum Dashboard which is full of interesting nuggets.

Back on topic, I suppose it all really depends what the £800 means to you. I've always tended to go out WTP and back in CW but of course there's no guarantee you'll get another offer or even any offer at the airport on the day.

See this thread for that.

In the meantime may I welcome you to Flyertalk and the BA Board Steven Vaughan.

As you can see already there are different opinions however at the moment seems more would take it so as the old saying goes in the Houses of Parliament

"The Aye's have it, the Aye's have it"
