Flap 30 is usual for 22L at JFK. Flap limiting speed for flap 30 is 180. At best they’ll be doing gear down flap 25 but Boeing don’t recommend using F25 as an intermediate setting. So gear down Flap 20. From 5 slow down to 170 before selecting flap 30 and still be stable at 1000’ is going to be tight. Not helped by the DME at us airfields showing 1.2 ish miles at touchdown.
