It is only a 25K mile bonus not a 75K mile bonus (50% of 50K is 25K). The total miles received on a 50K transfer is 75K including the bonus. But I still find value in this offer. I am flexible enough in many of my travels that I almost always can find low level awards. It is not easy and takes a ton of time, but it is possible. Fortunately I also can use AS (since many of my award trips are to Alaska) and fortunately through Feb 2011 I have unlimited changes to award tickets. And the stopover provision on domestic awards means if I transfer 67K miles I end up with 100K miles. With that number of miles I can basically get 6 or more trips from 4 domestic awards. That averages out to under 17K miles per trip. Note that in my mind "trip" and "award" mean different things.
And yes, the transfer fee is low. You only pay the tax that AmEx pays on the miles. The "transfer" itself is "free." Kind of like SPG to an airline program.
My guess is that since the MQM's are credited 4-6 weeks after the end of the program, they would be 2011 MQM's. 4-6 weeks after Dec 15th is well into 2011.
Sorry for any confusion. I was referring to the 75K miles, 50K transferred and 25K extra, as bonus miles to distinguish them from MQMs or BIS miles. I realize that the total is 75K, not 75K on top of the 50K transferred. I also calculated the transfer fee on the basis of the additional 75K miles available to be spent.
