I'm surprised at the impact this will have on my account. From May 1 to now I have ~65 segments and 73k miles. With the 500 min and 100% bonus miles I get just under 40k miles. It looks like booking a ton of flights prior to 8/6 and getting the bonus miles for those flights sheilded me from the true impact of the now recinded changes.
If asked prior to the press release, I would have guessed closer to 60k miles.
