Hi Paulo! I just traveled this Thursday from JFK. The Airport is very safe. You should just try to find a place with good seats to rest. Also comment that the flow of people is increasing .. even so it is nothing compared to normality. There are terminals that look totally empty! Regarding your second question. Delta is located in terminal 4 (you will also find Latam there). I tell you that during the whole trip you should wear the mask (you can only remove it to eat, so I recommend you look for a very comfortable one. I hope it does not hook in the ears but behind the neck, I assure you that you will remember me with this tip) I hope my answers have helped you. Success!! And have a good trip!
You do the security if you do not want to catch any virus, use the necessary instruments and follow the instructions that the airport gives you, remember that after November 4 you have to bring a negative covid test carried out 3 days before the flight
