Perusing the schedule they seem to be strewn about on quite a number of dates in October. Right now the 8:40AM and 11:40AM SFO-BOS flights are showing Int'l 763's. The 6:30AM and 6:20PM BOS-SFO flights are showing Int'l 763 service on the return.
This route has been primarily 757's for a long time now. it's nice to see 763's back on this route. Now if they could only put a few on the LAX-BOS-LAX runs!
