On a single ticket, Minimum Connection Time (MCT) at JFK for this Connection is 1h25. That’s super-tight but it means that your connection still easily meets MCT and therefore your connection is protected, should you miss it. As always, that means you’ll get on the next flight with seats available.

These things are never risk-free, but you should still be ok with 2h45. Everyone has different attitudes to risk, and if you want to change I would look at the options available first and see if any of them make you happier. Also take a screen shot of the warning, you may or may not get resistance to a change with a connection standing at 2h45.

If you decide to go with it, your Virgin flight will arrive at T4 and your onward domestic will depart from either T4 or T2, it’s not easy to know in advance. If it turns out to be T2, it’s a little less convenient but perfectly manageable. After immigration, customs and bag drop in T4, go back through security at T4 and (if necessary) make the transfer to T2 on Delta’s airside bus, called The Jitney. It’s the only airside connection between terminals at JFK.
