I am hoping to directly benefit from the exact same idea over the upcoming year with domestic CE. I wouldn't often pay for CE domestic on a stand alone trip as such, but am happy to make a small personal contribution for the extra TP's. The efficiency depends on the original allocated TP's, but after POUGing a domestic booking next week at £65, I make that circa £2.17/TP when upgraded from N. Not too shabby really for the odd occasion
