I thought about the airline as well, noting that I did not get approval in November until I was at the airport and not that long from needing to board. My thought is you either have approval or don't, I would like to think that the approval forms would make the difference but I do remember AA looking at the dates listed. So not only are you depending upon SXM to get the info to us correctly but they need to get it to the airlines as well. I still fully expect it to be the 120 hours.
Cheers and good luck,
