"The original plan was to arrive around 4pm, but I didn't realize that Mesaba will non-rev you to you're interview. If you are not familiar with this, essentially it means that you will fly standby and will probably not get there when you expect to." Quote from previous post above.

Incorrect. Mesaba will positive space you, which is different from non-reving in the purest sense. Positive spacing is in a sense an actual assignment of a seat, where as non reving is listing for a flight, and being a low priority standby passenger. Code 5 i believe
