Hello, I'm flying on DL31 from Moscow to JFK on Sat. and then from JFK to Las Vegas. In my ticket it's mentioned in both ways- Terminal 3. But in my Delta account I see that I arrive to JFK (gate 09), and leave to Vegas from gate B20. Does it mean that I leave from terminal 4? Or in Terminal 3 there's a gate B20? If it is Terminal 4, how should I get there? And will I have time (I have only 1h50m between the flights)..Thanks!
Terminal 3 -- Terminal 4?
