Is anyone able to explain why travelnet shows Delta mainline as S3 on 9E flights, yet the standby priority code list shows that they should be at S3B1? I have checked multiple flights, only time I have seen a DL as S3B1 was on a Skywest standby list.

I'm not arguing what they should or shouldn't be at, just as to why the priority list shows one thing and the standby list shows another.
