I also bought a few of these fares back in May when they came out, 5 total. They are all for 2015 travel and will certainly help out for next years status qualification. Throughout the time, I've had some schedule changes, nothing major. However, one in particular gave me a very tight connection. I've had it corrected, but one thing I noticed in the process is that AA will not change the int'l portion, which is on US, to its own metal. I figured that between the time I bought the tickets and fly, there will be some schedule changes and I can call an change to a better schedule, well, so far, the 3 times I've tried, I have been turned down to switch the ORD-PHL-LHR on US to a ORD-LHR on AA. No big deal, at what I paid its not bad and not complaining.
