None of us know who will fly what in November. Come back a week before your trip if you want and options will be clearer but frankly, given number of seats in F it’s probably best not to overthink this and just go with the flow. Chances are you’ll be fine, and if not, it will all depend on what’s available on the day and why you are running late in the first place (weather, strike etc)

My polite way to say that whilst I understand the desire to “be prepared”, your trying to figure out where you stand now is essentially wasting your time and energy and worrying needlessly.
