I have already purchased five international trips for this year and I thought every weekend there were at least minor changes to schedules and/or equipment. However, I do not see such at this point.

Are the changes coming later or are we just in the 'eye of the storm'? BTW, of late SMS has worked hard to move schedule changes to my advantage in most cases. One flight is an I fare and the others are M fares using PMU/SWUs.
