All my flights so far are EDI-LON and booked by work on whatever system they use, so unfortunately not got any real option to adjust it. - combination of 5/10/20 TP depending on whatever bucket it is at the time.
I'm at 29/50 flights and 275TP so not the most! 2 more flights next week and year ends 8th July. Should get 2 trips a month to make it, but not guaranteed so looking at options
