I have a trip booked for a few months from now on Delta for BNA->LAX->SEA. Both flights are booked on the same type of equipment (737-800, coded 73H) and the second flight is scheduled to leave 40 minutes after the first arrives, but I'm curious whether the flights will be on the same 737-800 or not.
Obviously, it would be more convenient if the flights used the same aircraft, as this would mean not needing to quickly get to another gate and not having to worry about delays in the first flight possibly causing a missed connection.
I'm aware of options like flightradar24 and flightaware for tracking an inbound flight after the flight plan has been filed with the relevant civil aviation authority (i.e. usually just on the day of the flight,) but I'm specifically curious if there's any way to find out what aircraft is scheduled to fly a particular route much further in the future (i.e. a few months in this case.) While, in the case of schedules that remain constant all year, one could just look to see whether the same equipment was being used to operate both flights now or not, in many cases (including the one that prompted this question,) one or both of the flights involved isn't being operated right now (e.g. seasonal flights or flights that haven't started operations, yet.)
Of course, there's no guarantee that the equipment scheduled now will actually end up flying the route months from now, but it would be interesting to know which aircraft is scheduled, anyway.
