If you end up late and miss a trip, the company will look back and see if you meet the time equivalent of a legal duty period (The rule of thumb that I've used is, if I could operate it in and hubturn to my next trip, then I'd be okay). If you don't use Staging, and use Personal or Business to commute to work, then it doesn't apply, but if you miss a trip, you could be in jeopardy for discipline and loss of pay for that trip(s). There have been flight managers and ACPs in the past that have pretty much endorsed using B class to jumpseat, and folks would still be okay if a FedEx flight was late, though I know of no one that has tested this (by missing a trip). In any case, if you miss a trip other than using S class, or used S class but didn't meet the "artificial" duty requirement, or are scheduled to arrive less that 1+30 prior to your trip, you are not contractually protected from discipline/loss of pay. As long as you don't miss a trip, it shouldn't matter what jumpseat priority you use, but, obviously, the 777 FC interprets that differently.

I have missed one trip while using Staging class in 14 yrs, hung out for 3 days trying to do MU. No one called/emailed and asked about it. It was handled all through CRS. You do need to, if possible, keep CRS updated, but I know plenty of folks that have been okay after getting to MEM late without a single call to CRS.

In summation, to be able to use S, you need the 13+30 (jump seat flight + plus your trip), 1+30 between jumpseat block in and your trip showtime, and you need to keep CRS up to date, if necessary. P and B have no such requirements, but you are on your own if you miss a trip.
