Quite possibly so. I am relaxed.

I'd rather it were WT+ on the way out and J on way back in many ways as I am doing my perennial trick of eking out my holiday to the last possible minute and going straight to the office. But it won't kill me.

It is however a reward booking, so I also don't know the mechanics of trying a cash upgrade from a reward booking. Certainly MMB hasn't let me even price it (had a go). So it may be something I have to phone for.
