For the PE upgrade from a Y/B Economy it only cost ~10k (maybe it was 12.5k) points (one way)
For the RL upgrade from a Y/B Economy it only cost 30k points (one way)

According to EVA's site (Requirements - EVA Air America) , for each one-way sector route, I believe the upgrade should have cost as follows:

For PE upgrade from Economy - 25k points (one way)
For RL upgrade from Economy - 60k points (one way)

So is there an undocumented rule that purchasing a more expensive Economy fare (i.e. Y/B) will require less points for upgrading?
