The delay in SLC for SLC-CDG inbound flight naturally cascaded into the delay on today's CDG-JFK flight.
Looks like it departed Amsterdam a half hour late en route to SLC where it landed 2.5 hours late. I would bet the jet stream was particularly strong on this flight (DL220 on 12/06/23) and that's why it landed 2.5 hours late. But that's just an assumption. Looks like the speed slowed down a bit:
