It looks like right now that flight is JFK 1165 and lands in Miami at 10:30 and then 1047 takes off at 11:30. But in October it will be 443 JFK that connects thru Miami on flight 1017? Between landing @10:30 and the 1017 flight which leaves at 11:15 you don't have too much of a window. Are the gates close between the 2 flights? Do you have to go thru security again once you deplane in Miami? I assume (bad word when it comes to flying) that AA does the luggage transfers from flight to flight.
The reason for picking that flight out of JFK is all the other flights require much longer travel time due to layovers except one flight that goes out of JFK at 5:40. I know that will not go over to good with my wife but maybe it is the safer option.
Thanks
