SWA flight routes

[sj24]

We will be flying SWA from Boston to Orlando in April. Is there a way to find out where the plane came from prior to getting on it in Boston? In other words I am wondering how many/if any people will be on the plane before we board, did it come from from Manchester then to Boston then to Philly then to Orlando. Trying to figure out if I should do the early check in or just do it at T-24. If the plane is empty in Boston then I think it wouldn't be worth it.

Should add that the flight #is 3876 and it goes from Bos to Philly, we change planes in Philly so there is a different flight # altogether.

Have you tried checking tickets from manchester to boston or manchester to philly and see if the same flight number is shown?
