Thinking about changing dates to increase my odds. Any anecdotal evidence to do so? Can go either Friday 12/14 or Saturday 12/15 - there are two flights per day morning and evening NRT-DFW on 772. All things being equal (no C available on anything, loads look similar (i.e., just a few seats taken on the maps and J7)), is one better than another to clear 4 EVIPs (attached to an EXP) and 1 miles plus co-pay (no status)?
