Both our flights for Sept 10th and return 24th MAN>SFO still showing 1-1-1 config. but strangely checking it just now a message pops up and says 'please note flight schedule change, if your ok with this do nothing' etc. but try as I might I cannot for the life of me see ANY change whatsoever !
For my flight on VS126 on September 1st, the arrival time has been changed. It was 12:05 PM: it is now 11:55 AM.
VS125 on 9/10 remains unchanged.
Seat maps are 1:1:1, but I expect that will change a couple of days before departure. A friend flew SFO-MAN-SFO earlier this month, and the seat map changed a few days before the flight. His original seat requests were thrown out with the change in seat map.
