Be careful. US does not offer mileage upgrades for discount transatlantic fares. The lowest transatlantic upgradeable (with miles) fare is B-class and they usually run $1,200 or more per roundtrip. And those fares will still cost you 20k each way to upgrade. Full fare coach ($2,000+) and full fare business class fares can be upgraded for 10k each way. </font>
Ah. didn't see the proviso there about B/C class fares. I assume B/C on US are similar to M/H on UA.
