Agree with Moomba ... an opportunity existed and you missed it.

That's why we keep close track of the cost of our previous flights ... if we see a decent deal, we book there and then. But, to be fair, we are always completely flexible on dates.
The one time we were a bit slow in booking ahead [over Christmas] the difference between a WT+ and CW fare was suddenly only about £300
We flew J, of course!
