Hi everyone, as the title says, let me explain a bit further.
I was booked on DL7276, DL6793, DL2332 & DL4272 (HBA-MEL-LAX-YOW) with the first two flights on VA metal .
My first flight departing "Hobart International"

on VA went mechanical and would be delayed by several hours. Delta re-booked me on the next available flight to MEL, which was on JQ. The rest of my trip went well.
I checked the mileage posted for this trip and the HBA-MEL segment wasn't posted, so I submitted a claim on the DL website and provided my original boarding passes etc. I got a message back saying the segment was ineligible.
Question.... Why would it be ineligible, I asked for credit based on the original itinerary? Should I try and submit the claim again?
