Have an upcoming return to BEG after Christmas. Prices were high when I booked, discount Y.

After dropping from Gold to Blue (curse these straitened times and ban on BA travel) my travel is now picking up again and in F on BA and AA.

I'm trying to time my 4th BA sector and juggling the points so that the next sector I do in F will be my 5th BA metal sector of my membership year and put me on 620TPs.

That means the next three BA/AA domestic F 2000+m sectors I do will see me 540 TPs to the good in requalifying for Silver or heading towards Gold again.

But for this to work, I need this ba.com £150 per sector upgrade into CE to earn 40TPs each way. Does it?
