Ironically my flight may be at 8:30pm, so is it a crapshoot? Actually , looking at their flight tracker, seems all flights today even late ones (though no 8:30) are from T5 like you said
Might fly from LGA, I think Jetblue is Terminal B and so is the Sapphire lounge . I dont think they have other lounges
That's probably for international flights, per this Reddit discussion (although I would expect it to be for arrivals, not departures).
Why does jetBlue use Terminal 4 at JFK for intl arrivals at night, when they use terminal 5 throughout the day? : r/jetblue
And yes, JetBlue is in the LGA terminal with the Sapphire lounge. Not sure about wait times there, since it's the only PP lounge.
