But, I thought on British Airways's web-site it says that a transatlantic flight from N. America to Europe costs 50,000 miles. Am I correct in assuming that BA wouldn't take 50,000 of your AA miles to fly with them on a transatlantic flight, but would take 30,000 or some other similar converted amount? Does anyone know the conversion between AA and the other Oneworld Partners?
I speculate that the difference is due to the different units in use. This is my pure speculation and it seems to be supported by the numbers you listed. I admit that I did not check records to verify it. Folks with more knowledge please correct me if I am wrong.
Here is a bit more detail of my speculation. Mile is a prevailing distance unit in the United States, but pretty much in all of the rest of the world, the prevailing distance unit is Kilometer. The mileage of most FF programs of many Asian or European airlines is actually based on Kilometer. But people tend to use Mile when they really mean Kilometer, probably because the Americans use Mile, and also because "Mile" is shorter and easier to say than "Kilometer". The relation between these two units are: 1 Mile = 1.6 Kilometer. So 30,000 AA Mile ~= 50,000 BA Mile, and hence the AA award and the BA award are roughly at the same level. Remember what I just said, BA Mile probably means Kilometer.
