Y Fare, M fare?

Hiya,
I've a rake of miles (about 70,000) and I'm considering going to NYC with the missus in June for my birthday. Looking at the info I reckon upgrading from economy to UC one way and PE the other is feasible. My question is, do you good people think it will be possible and will the cheapest necessary economy tickets be any cheaper than the "Y" ones shown on the VS website as the flexible fares on the days in question? Sorry for appearing cheap, but I am!!! ?|
