I'm interested in jumpseating from Hyannis to Nantucket tomorrow, Wednesday Aug 14. Thinking of doing just a day trip out there. Are there normally seats available throughout the day? I put a load request in on StaffTraveler. Waiting on that request for now. If I do jumpseat tomorrow is there any special procedure required to get listed? Is the dress attire still the standard business casual as it is for most airlines?

Thanks!
