I had no trip it was touching or would drop. I had one white slip in for any one day and on that one I had checked the box to not fly into the next month (need hours for GS trigger). When I saw this two day trip that went into the next month it had high block time on the first day. I submitted a second white slip specifically asking for that trip by trip number. I called scheduling right afterwards and they said they would look at it when they run it. Next thing I see it goes out as a green slip and when I call scheduling I am told it was because I didn’t select to fly into the next month on the white slip request. That option isn’t available when you select a trip by number.
