Happy New Year all

I am just about to book a RFS from LGW to TFS but cant decide between Economy and Club Europe. We already have lounge access so the main benefit for us will the extra width I realise there is no extra leg room.

If we book Economy I would pay for extra leg room what is the cost of this on this route please. I can only find FROM £7
If we booked Club I would not reserve seats.

I am just comparing the difference in total costs.

Thanks in advance.
