We are flying DFW-JFK in F (7:50am - 12:28pm) and then JFK-MXP in J (7:30pm - 9:50am) All in the same day but booked as 2 separate tickets. Not sure what our process will be for when we land in JFK, regarding checked luggage, security, and checking in for our international flight at JFK (especially with negative covid test and other documentation). Can anyone provide any insight in what we will need to do at each departing airport? Also I know that since the tickets are booked separately they cannot be combined on the same itinerary, but would it help for me to call Delta and have them make note that we do have a connecting flight in JFK, in case there are any delays with our first flight? Sorry for all of the questions, I just have zero experience with multiple same day flights and also flying internationally.
