HPN
Is bite size 5 gates I think and there so close to each other the planes don't fit near the door you walk up to your plane I don't know anyone who has tried but you can probably figure out a way to board the wrong plane. no lounges, but free wifi that's actually fast
PBI
Is fairly small but nothing compared to HPN (I remember when it was a outdoor airport) its basically shaped like an H I think,
with the middle line between the 2 concourses being before security there's actually some nice shops and couches to sit on in that middle part, I actually would prefer that area to a lot of airport lounges there's a putting green and pool table (for a fee) there as well, again this airport also has free wifi
