Is there a time requirement via the PWA (or any other formal agreement/rule) for having had a slip request submitted prior to a trip being awarded in order for you to have a legitimate claim at being skipped over and the trip being incorrectly awarded to another pilot? I had a GS request in for a specific rotation and it went to another pilot (his #2) 16 minutes after the time stamp for my slip request. Appears the scheduler ignored my slip request.
