I was looking for a PDF timetable and was disappointed it is apparently no longer published. I'm trying to plan a trip that would ideally involve a flight segment from SPN-NRT, a route that appears to operate only on certain days. It would be helpful to me to see what days it operates without having to run a bunch of "dummy" flight searches. Would there be some reason for United hide a proper timetable from the public or keep it "secret"?
